What’s new about social media?


According to dweinberger:


I’m on a panel about “What’s Next in Social Media?” at the National Archives tonight , moderated by Alex Howard, the Government 2.0 Correspondent for O’Reilly Media, and with fellow panelists Sarah Bernard, Deputy Director, White House Office of Digital Strategy; Pamela S. Wright, Chief Digital Access Strategist at the National Archives. It’s at 7pm, with a “social media fair” beginning at 5:30pm.

I don’t know if we’re going to be asked to give brief opening statements. I suspect not. But, if so I’m thinking of talking about the context, because I don’t know what social media will be:

1. The Internet began as an open “address space” that enabled networks to be created within it. So, we got the Web, which networked pages. We got social networks, which networked people. We are well on our way to networking data, through the Semantic Web and Linked Open Data. We are getting an Internet of Things. The DPLA will, I hope, help create a network of cultural objects.

2. The Internet and the Web have always been social, but the rise of networks particularly tuned to social needs is of vast importance because the social determines all the rest. Indeed, the Internet is a medium only because we are in fact that through which messages pass. We pass them along because they matter to us, and we stake a bit of selves on them. We are the medium.

3. Of all of the major and transformative networks that have emerged, only the social networks are closed and owned. I don’t know how or if we will get open social networks, but it is a danger that as of now we do not have them.

Textuality with Roland Barthes


In S/Z , Roland Barthes describes an ideal textuality that precisely matches that which has come to be called computer hypertext -- text composed of blocks of words (or images) linked electronically by multiple paths, chains, or trails in an open-ended, perpetually unfinished textuality described by the terms link, node, network, web , and path: "In this ideal text," says Barthes,

the networks [réseaux ] are many and interact, without any one of them being able to surpass the rest; this text is a galaxy of signifiers, not a structure of signifieds; it has no beginning; it is reversible; we gain access to it by several entrances, none of which can be authoritatively declared to be the main one; the codes it mobilizes extend as far as the eye can reach, they are indeterminable . . . ; the systems of meaning can take over this absolutely plural text, but their number is never closed, based as it is on the infinity of language" (emphasis in original; 5-6 ).

Network analysis


Network analysis is the study of social relations among a set of actors. It is a field of study -- a set of phenomena or data which we seek to understand.

In the process of working in this field, network researchers have developed a set of distinctive theoretical perspectives as well. Some of the hallmarks of these perspectives are:

  • focus on relationships between actors rather than attributes of actors
  • sense of interdependence: a molecular rather atomistic view
  • structure affects substantive outcomes
  • emergent effects

Network theory is sympathetic with systems theory and complexity theory.

Social networks is also characterized by a distinctive methodology encompassing techniques for collecting data, statistical analysis, visual representation, etc.

Social Relations

Social relations can be thought of as dyadic attributes. Whereas mainstream social science is concerned with monadic attributes (e.g., income, age, sex, etc.), network analysis is concerned with attributes of pairs of individuals, of which binary relations are the main kind. Some examples of dyadic attributes:

  • Kinship: brother of, father of
  • Social Roles: boss of, teacher of, friend of
  • Affective: likes, respects, hates
  • Cognitive: knows, views as similar
  • Actions: talks to, has lunch with, attacks
  • Flows: number of cars moving between
  • Distance: number of miles between
  • Co-occurrence: is in the same club as, has the same color hair as
  • Mathematical: is two links removed from

Topics

1. Substantive effects of social network variables

  • Attributes of ego network --> access to resources, mental/physical health
  • Network closeness --> influence, diffusion
  • Similarity of position --> similarity of risks, opportunities, outcomes

2. Substantive determinants of social network variables

  • Personality --> centrality?
  • Similarity --> friendship ties? (Homophily)
  • Reduction of cognitive dissonance --> transitivity?
  • Strategic "networking"

3. Network determinants of network variables

  • Relationship between density and centrality

Internet is not WWW

Internet and World Wide Web – are they the same thing?

The Internet and the World Wide Web are not one and the same. The Internet is a collection of interconnected computer networks linked by copper wires, fiber-optic cables, wireless connections, etc.

In contrast, the Web is a collection of interconnected documents and other resources, linked by hyperlinks and URLs. The World Wide Web is one of the services accessible via the Internet, along with various others including e-mail, file sharing, online gaming, etc.
However, for all practical purposes and in everyday conversation, they are considered one and the same. In fact, dictionaries and thesauruses often fail to make any distinction.

Collaborative innovation


A question. What connects Facebook enthusiasts in China busy translating the social networking site into Mandarin and a community of orthopaedic surgeons swapping ideas on how to treat spinal injuries?

Facebook has called on its network of users to create new innovations to the site.


The answer. They're both examples of a worldwide phenomenon that is changing the way people -- and ultimately businesses -- develop ideas.
Collaborative Innovation Networks (COINs) are online communities of like-minded people working together to create innovations. Author and scientist Peter Gloor originated the term. He describes it as a "cyberteam of self-motivated people with a collective vision."
These cyberteams are cropping up everywhere, unified not only by their "collective vision" but by the giant tentacles of the Internet.
In the case of Facebook, they are the Chinese users of the site who are helping to translate it into their native language. Elsewhere, they are the surgeons collaborating on SpineConnect, an online community where experts from around the world can exchange ideas for innovations in the treatment of spinal injuries.


The potential of all this pooling of ideas is enormous, says Gloor.
If you're not convinced, he says, take a look at what COINs have already accomplished -- the creation of the World Wide Web itself is the most obvious example.
"It was developed by a network of people based all over the world working as a COIN," says Gloor, who ought to know since he was there for part of its inception.
Gloor was as a researcher at the Massachusetts Institute of Technology (MIT) in Boston 15 years ago at the same time as British scientist Tim Berners-Lee -- the man credited with inventing the Web.
Berners-Lee had come over to the U.S. from CERN, the European Particle Physics Laboratory in Switzerland where the Web had first launched three years earlier.
"I had the benefit of watching him work close up for a few months, and I saw that his real genius lay in his ability to co-ordinate and incorporate the ideas of all these hundreds of other people based around the world."

Since then COINs have helped create much of our online landscape.
The Web-based encyclopaedia Wikipedia and the Internet browser Mozilla Firefox are just two of the products whose development relies upon the contribution of a community of online users.
Gloor says: "I have a saying: 'Don't be a star, be a galaxy.' If you embed yourself in a galaxy you can go so much further."


But Gloor, who is from Switzerland, is not simply a delighted observer of the phenomenon. He was part of the network that helped develop hypertext -- online text that links to other text, like this. He worked with a hardcore of around 100 people worldwide, most of whom he never met and who worked on the project in their own time, and for little or no reward.
"Most of the innovation that you see on the Internet today was given away for nothing," he says. "People did it for the sheer love of it."


This fraternal, almost unworldly attitude is a common feature of many COINs. For the network to be successful, contributors have to operate transparently and be willing to share their knowledge.


This philanthropic, non-hierarchical approach to innovation sounds radical in an era when the theft of ideas by unscrupulous corporations is well documented.
However, Gloor says the concept has a strong historical precedent in the 'Junto' organization set up in Philadelphia by Benjamin Franklin in the 18th century. One of the Founding Fathers and a scientist by profession, Franklin set up the club for mutual improvement to allow people from diverse backgrounds to share knowledge and propose ideas.


Of course the idea of working collaboratively to create innovations is not new. Taking just one example, the development of much of modern physics (from quantum theory to the creation of the atom bomb) owes its success to teamwork. The Manhattan Project, for example, employed more than 130,000 people at over thirty different sites across North America and Europe.
Even so, it is an approach that the business world has found hard to come to terms with.
Gloor says the rigid structure of many big corporations makes this free exchange of ideas difficult to achieve. "In order to gain control, one has to give up control. But the one thing managers don't like doing is giving up control."


A case in point is the failure of Xerox to take advantage of the myriad of innovations produced at the company's research facility in the 1970s and early 1980s.
The R&D centre known as Xerox PARC and located in Palo Alto, California, was responsible for inventing laser printing and the Ethernet, and for pioneering the use of the computer mouse. Xerox executives failed to grasp the potential of many of PARC's inventions and it was left to other firms to develop them fully, and enjoy the profits.
Not all firms have been quite so sluggish.


Procter and Gamble, the world's biggest maker of household goods, made a commitment in 2001 to source half of all new innovations from outside of the company. It set up 'Connect + Develop', an initiative that allows people to submit new innovations online.
The venture has been so successful that P&G now gets 42 percent of all its new technologies from outside sources.

Intellectual abilities


Connectionism is a movement in cognitive science which hopes to explain human intellectual abilities using artificial neural networks (also known as ‘neural networks’ or ‘neural nets’).

Neural networks are simplified models of the brain composed of large numbers of units (the analogs of neurons) together with weights that measure the strength of connections between the units. These weights model the effects of the synapses that link one neuron to another. Experiments on models of this kind have demonstrated an ability to learn such skills as face recognition, reading, and the detection of simple grammatical structure.

Philosophers have become interested in connectionism because it promises to provide an alternative to the classical theory of the mind: the widely held view that the mind is something akin to a digital computer processing a symbolic language. Exactly how and to what extent the connectionist paradigm constitutes a challenge to classicism has been a matter of hot debate in recent years.

Woven threads


If we look at the original meaning of network, we find that it refers to a fabric of twisted or woven threads that have spaces in them, as would a net.

Those threads and open spaces are an apt metaphor for hypertext where all spaces are connected, linked, and no space is any more important than another.
