network. really the only criticism i have for the whole dealcy think they sold it for too little. blogging platforms have huge, huge potential and they have fantastic engagement as well. >> so if you look in the future, could tumblr have sold for not 1 bnt $1 billion but tens of billions? matt says this was very bittersweet. this kind of platform, you look in the future, it could be very, very successful and for advertisers, too. >> we know there is a lot of adult content on tumblr. should users expect big changes? >> he was a little bit awkward about that answer. i thought maybe it was because i'm asking him about the porn problem in front of his mother. what he said was nothing's going to change. those guidelines are strict. but i think it is going to take time. people post a lot of times illegal material on tumblr. now it is part of a big public company. you just can't ignore that now.
