Google has 45 accounts on Twitter: why not just buy them?

Spammers have thousands of accounts each on Twitter. I don't see anyone suggesting that they should spend a billion dollars to buy the service.

What reason would Google possibly have for ever buying Twitter? I would hope they're gun-shy on large acquisitions after picking up the money sink they call YouTube. At least YouTube has some kind of revenue.

A purchase of Twitter just comes with a huge spam/junk problem and a reputation for technical problems.

I'm honestly not sure if this is a brilliant parody of TechCrunch style "journalism" or just the echo chamber that produces quotes like "Google, which probably wants to buy Twitter just because it’s hot".

Does Twitter even make money? Buying them would end up just like youtube.
