Facebook loves to talk about its ridiculously high number of users. Yes, Facebook has a whole lot of accounts, but many of them aren't humans. eMarketer released an analysis of Facebook's audience, and it turns out more than 10 percent of Facebook's reported monthly users are not human. Over 100 million active Facebook users are pets, objects or brands.

At the end of March, Facebook announced that it has 1.11 billion monthly active users. eMarketer found that only 889.3 million of those users were humans.

Yahoo is considering buying Tumblr, according to two separate reports on AllThingsD and Adweek. It's eyeing the one social network it can afford that would make Yahoo feel young again.

Both cite a valuation of $1 billion. The site, known for cat GIFs and amateur porn, expects to turn its first profit this year.

One described the Syrian rebel group Jabhat al-Nusra as terrorists and linked to a graphic video of a hooded man shooting kneeling prisoners in the back of the head.
