Google should definitely buy twitter. Knowing the google guys, they'd make it so much better and find a way to integrate it with there own stuff.
I dont think facebook would buy twitter. Facebook has already implented twitter-ish features into its site already. Google wants twitter for knowing what trends are and what people are looking out for, not neccesary money made from it (Although they will do that for sure).
Facebook isn't really a corporation, so they couldn't buy Twitter, plus they are in direct competition of each other, such as an acquisition would make no sense. Google hardly has a monopoly on the internet, maybe the people using that term should look it up, but they don't really have a service like it, it costs a lot to keep up, though, and might just be a fad. I should think that Microsoft would horde up some money, now they don't have anything to worry about in this recession. Yahoo! wouldn't begin to have enough money for it. Myspace is also a competitor of Twitter's, so yeah. Google is the only one who could buy it, and they probably won't.
ehem!just saying. Why would Google wanna buy Twitter anyway? Don't they already own Orkut. Why another Social webbie? Maybe in this case Microsoft would be a better choice so they could establish better online?
Unless Twitter finally come up with some way to generate CRAPLOAD of money FAST so they can afford better servers then I guess Google should take them. I mean seriously, site is really unstable and been like it for a while now.
I don't like the idea of Google buying Twitter. Google would monopolize internet and thus making it more harder for us.
