Why Yahoo! buy Flickr?

I'm not a consultor so I may be wrong -uf!, it's fine to know one can do mistakes from time to time in this world- but I my opinion, Yahoo! is building 360º and now is buying Flickr not just to follow Google.

They both, Google and Yahoo! leave time ago searching as a bussines focus. Why being processing information if we can produce information. Something like you put cameras, I put the war. They don't produce information but they are closer, they are where contents are done, nowadays at blogging communities. If you got information, you got power, have ever think about how much infor has Google & Yahoo! ? I repeat, not just 'cause they search and index the web, thought about they blogging services (Blogger), mail (mainly Gmail), mail-list (Yahoo Groups), free site (Geocities) ... for sure there're a lot of useless info inside this contents, but ... thought about it for a while...
