The 25 Most Popular Tumblrs Reveal the Challenge for Yahoo! - Businessweek

Sign of the times

"Tumblr has been quietly chopping down on the smut, and only one of its top 25 sites today is pornographic, according to Quantcast.
The rest of Tumblr’s most popular blogs are SFW, but they’re not exactly mainstream. The single most-visited Tumblr is dedicated to Minecraft, followed by a Portuguese-language site specializing in animated GIFS and one that translates people’s names into various languages spoken on science fiction shows. Professional media outlets and brands make up three of the top 25 (Comedy Central; Clarin, the Argentine newspaper; and Angry Birds). Other particularly popular sites are a blog juxtaposing handsome men and adorable kittens; a blog shaming people who act like douchebags on other social-media platforms; and various collections of cartoons."
