Just wrote about this in Smartmobs - Google Jaiku - that Google buys social mobile startup Jaiku (according to TechCrunch).

I'm still getting a lot of Dodgeball messaging but I never really figured out how to use Dodgeball for anything much useful.  In fact, Dodgeball tells me where someone is or has been, but not where they're going to be in 30 minutes - which doesn't give me enough time to meetup, unless, the person I'm meeting up with is a still as a rock.

According to TechCrunch:

"..There will be inevitable comparison’s with Google’s acquisition of Dodgeball, which largely came to nothing, but it would appear that the time for social networking and blogging via mobile has come. Google’s ability to add scale and marketing muscle to Jaiku should be putting Twitter on the back-foot right now."

Dodgeball came to nothing because Dodgeball doesn't do much of anything.  Don't know anything much about Jaiku, but I bet I soon will know more about it, now that the big G has bought it.
