To that end, I urge all of you to follow Technology Review on Twitter. "We conjecture that for these users Twitter is rather a source of information than a social networking site."Īnother possibility, left unexplored by Kwak and his colleagues, is simply that on Twitter, like real life, some people are much more popular than others.Īside from its monkey + keyboard simplicity, the fact that links on Twitter do not have to be reciprocal may be its ultimate genius. "67.6% of users are not followed by any of their followings in Twitter," they report. There Are a Lot of Lonely People on TwitterĬlashing with the service's interconnectivity, Kwak et al.'s analysis also suggests that there are a lot of lonely people on Twitter, and not just the ones who are tweeting angry political screeds at 8 pm on a Saturday night. Owing to the short path length between any two users, news travels fast in the tweet-o-sphere.Įarlier work suggested that the best way to get noticed on Twitter was to tweet at certain times of day, and Kwak et al.'s paper sheds some light on why this is the case: "Half of retweeting occurs within an hour, and 75% under a day." And it's those initial re-tweets that make all the difference: "What is interesting is from the second hop and on is that the retweets two hops or more away from the source are much more responsive and basically occur back to back up to 5 hops away." But it appears that the (so far) still entirely human-filtered paradise of Twitter may come to the rescue. These days we have to contend with the creeping power of what can only notionally be defined as media "content"-produced purely to appear at the top of search results. If this reminds of you early 90's hyperbole about the then-new world wide web, it should! Back then the web was a raucous, disorganized, largely volunteer-led effort full of surprisingly informative Geocities pages and equally uninformative corporate websites. "That is, the mechanism of retweet has given every user the power to spread information broadly Individual users have the power to dictate which information is important and should spread by the form of retweet In a way we are witnessing the emergence of collective intelligence." ".No matter how many followers a user has, the tweet is likely to reach once the user's tweet starts spreading via retweets," says Kwak et al. What's more, because 94% of the users on Twitter are fewer than five degrees of separation from one another, it's likely that the distance between any random Joe or Jane and say, Bill Gates, is even shorter on Twitter than in real life. In fact, the average path length on Twitter is 4.12. hypothesized that because only 22.1% of links are reciprocal (that is, I follow you, and you follow me as well) the number of degrees separating users would be longer. On the MSN messenger network of 180 million users, for example, the median degree of separation is 6. The ideas behind Stanley Milgram's original "six degrees of separation" experiment, which suggested that any two people on earth could be connected by at most six hops from one acquaintance to the next, have been widely applied to online social networks. ![]() When a message is retweeted just a few times it reaches a huge number of users. This "retweet tree analysis" shows instances of retweeting.
