Congrats, guys! This is exciting... Jaiku, for those of you who don't know, is like twitter (and if you don't know twitter... well SHEESH!) as a system for providing "updates" - or "microblogging" - only cooler. It also happens to be where two of my smartest friends termie and ralphm work. Jaiku, amongst other cool things, has bit better concept of 'presense' than twitter and are doing some cool work with XMPP on the backend.
Early speculation as to what GOOG has in mind for Jaiku is just that... early speculation. I'll be anxiously waiting to see what comes from the acquisition. In the meantime, as a happy side-effect, Andy is moving back to SF... can't wait for our next adventures in California :)
