The engine of internet culture is chugging along, changed. ​​​​ --- While porn creators belonged to tightly connected subgroups, they were linked to the rest of Tumblr’s network “with a very high number of ties,” and their productions “spread widely across the whole social graph.” In other words, they weren’t quarantined in some illicit corner of the site—they were woven into its basic fabric: The average Tumblr user in the sample followed 51 blogs, two or three of which tended to be specifically pornographic, and another two of which tended to be “bridge” blogs, run by users who were particularly likely to reblog porn. […] Plenty of new, younger fandoms sprung up on Tumblr this year, according to Brennan, but it’s notable how much of what showed up on the year-end list for what has always been the most creative and arguably the most important platform on the web was regurgitated from other sites—or bland continuations of aesthetically unchallenging trends that have been popular for years. (Like the biggest pop star in the world.) Tumblr can still be funny and strange, and there is still no better place on the internet to be a fan of something, explore a social or sexual identity, or reblog a convoluted joke about being young and online.
