I really can't wrap my head around Yahoo! buying tumblr. I don't know if there was any news leading up to the buy out, but it just seems like a spur of the moment type thing. I don't know. This could turn out to be the best thing that has ever happened to tumblr or the worst thing possible. I just hope Yahoo! keeps to their promise and doesn't drastically try to change anything. Similar to Instagram after Facebook bought it, I hope they keep it running independently.
About Flickr, was that ever really popular though?
