Yahoo/Tumblr (YHOO +0.7%) roundup: 1) Yahoo promises Tumblr will "enhance EBITDA and revenue" next year. Marissa Mayer states Yahoo could introduce ads on Tumblr's blog feed, and also on individual blogs (with a blogger's permission). 2) Some Tumblr users aren't happy with the deal, and rival WordPress reports taking in some defectors. 3) Yahoo claims Tumblr gets 75M new blog posts each day, and that over half its mobile users are using its apps. 4) In criticizing the deal, John Saroff argues traditional display ads don't suit Tumblr well. John Batelle thinks that's fine, since Tumblr is great for native ads. (previous)
