When i saw this image on Yahoo's soon to be released "twitter-killer" page, i immediately imagined a conversation inside Yahoo that went something like this:

Yahoo exec: why the image of a bunch of dumb dogs?

Yahoo marketing person: "well, twitter has a bird so we figured we'd have a few dogs."

Yahoo exec: brilliant!

I signed up, went to their popular section, saw bunch of soft porn at the top, closed my browser tab, never went back.

Nice way to keep the serious users away.

@ Eric: It is just that they are too dumb to look out of their windows and understand the reality of the internet and Twitter

I once made a "D" in an advertising class.

Now I understand why.
