Why Google or Yahoo should buy Twitter.

Does anyone agree with this? I don't think brevity implies a greater density of information; often it means there's none at all.

There's no context to real-time information, no opportunity for its audience to either discuss or ignore it, and therefore no way to judge its relevance. The author seems to feel that the sheer newness of a Twitter feed guarantees its importance, but I think the chances of 140 characters written five minutes ago being more relevant than the topmost Google result is close to nil.

does twitter hold any patents? i read a while back that software patents don't apply unless they are somehow linked to hardware.
