How Big is Tumblr

In Feb 2007, yet another blogging/ micro-blogging platform, Tumblr, launched — adding to the many choices for casual and serious bloggers and micro-bloggers in an already crowded market, and going up against competitors such as WordPress.com. Tumblr came to the attention of Yahoo!, a company with a history of buying many great (and some not so great) startups then becoming a graveyard for some of them, due to neglect. What’s in the future is difficult to say since Yahoo! plans to let Tumblr remain mostly autonomous, with the primary exception of the latter now displaying Yahoo!-powered ads.
