The panic was barely lessened by CEO Marissa Mayer's promise to protect 'the richness and breadth of content available on Tumblr.' So I decided to take a look at what, exactly, Tumblr-ers have to lose - by visiting the community's most popular adult blogs, of course.

Yahoo's purchase of Tumblr has some devotees worried that what they love most about the micro-blogging platform - the GIF porn, obvs - will disappear.
