Is it really though? I wouldn't necessarily classify it as a microblogging or photo sharing platform. It's a good old fashioned social networking service which revolve around the world of profile pages. Early on they introduced photo albums and it became huge for photo sharing with your friends.

At the end of the day Flickr is about one thing, photos, and it needs to stay that way. Yahoo bought Tumblr, an actual microblogging platform, that's their way into the big social game.
