Google has acquired Jaiku, a microblogging ste remarkably like Twitter (though as one commenter notes, "Twitter seems to essentially be a communication/microblogging tool. Jaiku, on the other hand, seems to deal in what they call presence management i.e. consolidating the multiple activities/identities that one has around the 'net and collecting them all in one place.") What Twitter has, though, is users, which is norally what makes it a good acquisition. But Twitter was co-founded by Evan Williams, the creator of Blogger, which was acquired by Google. So maybe Google doesn't feel like making him rich - again.
