In case you didn't know, last year I took my time to finish my degree. I started studying Computer Science, then I left, then I had a chance to finish it and I did. My tutor suggested a project based on social networking that was theoretically about a big media group that wanted to retrieve information from viewers, and it turned little by little in a recommender system. It was hard, as most projects, as it started like a thing without any aim and the objectives of what I was doing were clear only when my project was really advanced... meaning that I really didn't know that I was doing a recommender system, or what a recommender system was, until later, much later. Anyway, I took that topic as social networking is something I've always been fascinated with, and why not, to learn about some other languages, protocols... stuff.
Aaand I realized that there are some things about social networking that are, let's say, problematic. Or, better said, about the perception of social networks. I'm going to tell, informally, what it was about.
First things first: every social network has its uses, or at least the successful social networks. Obvious, but also more subtle that it seems. At first sight, Twitter is for short messages (and short term memory), Facebook for a wide approach of social network, Last.fm is for music connections, and Flickr about fans of photography. You take a deeper look at the contents, however, and find other things: Twitter is about opinions and journalism, Flickr is about geography mostly, Last.fm social networking works best when it's about live shows, and Facebook is a collection of preferences and hobbies. This, of course, means that Facebook is a great tool to gather interests for a recommender system. Actually, I took the "likes" from users as the reliable information, and it mostly worked.
More subtleties arise. A user behaves in a different manner depending on the social network, and by user I mean, you, me, your friend, or that famous DJ. Twitter is for shouting what you think people must read (via yourself, via your links, via retweet), Facebook is for carefully building your personality highlighting things (links, pictures) and giving your opinions, Flickr is to reflect your pure view of the world (in a manner that is both geographical and artistic information) and Tumblr, well, Tumblr is for porn. Just to name a few.
Also, I had the feeling that some social networks are, let's say, overcovered by the media. It is - or it was - the next big thing, the repository of global information, a mine of pure data, cheap, even a survey substitute. But, as the great concept of "Circles" that Google+ left, we only have information of our circles in social networks. This, again, is something obvious but forgotten many times: from your facebook account with hundreds of friends, or from your Twitter account with your thousands of followers, you only see one part of the world. As a social profile owner, you made the first filter and unlike family and "real life" relations, one usually joins similar people on those networks, with similar tastes, similar thoughts, or at least similar way of seeing the world - leftist or rightist, pop lover or drum n bass lover. This has happened before in the previous versions of social networks, that is, mail lists and forum boards, where a kind of humor arises and become part of that small community, but with those Twitter, Facebook accounts that seem more open and less restrictive it happens the same way. What is my point? Journalists distort reality through their Twitter account and usually share opinions based on only what they see, thinking that what they see is the most accurate reality. And journalism is the main source of opinion about social networking and such: what is a trend and what is not, what is more used and what is not, etc.
Twitter, of all the social networks, is the one I find most fascinating. Not only for what it meant in international revolts like the egyptian ones, but as its potential use as a manipulative tool and how frustrating is for so many companies to try to use this for their own means and not being able to. This sounds like a conspiration theory of big companies, but funny enough, this is not my vision, but of the "experts", let's say; they don't believe that it's possible that some trends are created freely, without any outside interaction, without any giant company teamed up with a political force gracely disguising their touch. The answer is that not exactly freewill, but a kind of "law of the tribe" exists in Twitter. Firstly, this is an incredibly democractic social network: every user has the same (potential) importance and can talk with any other unique user, famous or not, director or actor or friend, but of course some users are more read than others. Who are more read? Of course famous people, but there is a subtle difference between the ammount of readers and the ammount of traffic (i.e.: influence) a twitter account could make: a football player mostly tweets about "we are on the bus", "we are celebrating", "what a game!" and so on. An influencial twitter account is wittier, more intelligent, able to blend a funny remark and a critical opinion in 140 characters, and influencial people form influencial groups which are fed by themselves and by the people who want to be popular and influential too.
This is great, because, for once, money hasn't anything to do with it, and intelligence does, but journalists sometimes misunderstand the consequences. For example, the egyptian revolts were mostly organized by twitter, which is something they couldn't understand. And the 15-M protests were too, and this is when Twitter became a news story itself, with internet based newspapers having a section talking about the latest trending topic. But then, Twitter potential influence is restricted to Twitter users, and among them all, users who understand the Twitter quick currents of information. I feel like I'm being Captain Obvious here, but going at what I wrote before, a user only sees what the user wants to see, and this isn't the whole... and journalism sometimes forget this: tech writers that gather opinions from their circle of known people and go to quick conclussions about The Future Of Things To Come, political analysts that believe that a cold reception in Twitter means something, and gossip magazines that... ok, gossip magazines are in their territory after all. But what is the use of having Twitter related news of the trending topic? It's like the news of a gentlemen club most people are not allowed in: Twitter is difficult to understand and easy to feel alienated by it. It's wishful thinking to say that people all around the world of all classes are conected by the news on Twitter, and it's naive to say that you can recognize the world's problems in this social network, and a journalist not only should know that, but must avoid analyzing news via his own world: among all the jobs, a journalist should be the one worried about having the most diverese vision of things. Again, I repeat myself: a social network does not have it.
