M.I.T. Meets Tumblr: The Anatomy of a Forgotten Social NetworkPosted: April 2, 2014 | |
“One interesting question is whether Tumblr more closely resembles a blogosphere network than a microblogging network like that of Twitter.”
But in the rush, one network has been more or less ignored by researchers: Tumblr, a microblogging platform similar to Twitter. So an interesting question is how the network associated with Tumblr is different from the Twitter network.
Today we get an answer thanks to the work of Yi Chang and pals at Yahoo Labs in Sunnyvale. These guys point out that relatively little is known about Tumblr compared to other networks like Twitter and set out to change this.
The basic statistics are straightforward. Tumblr is a microblogging service with about 160 million users who together have published over 70 billion posts.
The most significant difference between Tumblr and its bigger cousin, Twitter, is that there is no limit to the size of the posts that users can create. By contrast, Twitter imposes the famous 140-character limit on all of its posts. Tumblr also supports multimedia posts, such as images, audio, and video.
Another important difference is that Tumblr does not require users to fill in basic profile information, such as gender or location. So this makes the analysis a little trickier than it is with other networks that do collect this information. Nevertheless, Chang and co say that Tumblr users tend to be much younger than people on other networks, with the majority of users being under the age of 25.
Chang and co study the nature of Tumblr using a subset of almost 600 million posts published on the network between August and September last year. They say that over 90 percent of these posts involve photos or text. Despite supporting other types of media, these have clearly not yet become popular on Tumblr.
One interesting question is whether Tumblr more closely resembles a blogosphere network than a microblogging network like that of Twitter.
There are significant differences between these types of network. A key characteristic of Twitter is that there is a good deal of reciprocity between users. Reciprocity is the likelihood that if user a follows user b, then b also follows a.
In the blogosphere, reciprocity is almost non-existent. Only 3 percent of bloggers have this kind of reciprocal link. On Twitter, however, the ratio is much higher: some 22 percent of tweeters have reciprocal links…read more…
