“Jaiku is now a part of Google. For more details about Jaiku and Google, see the Q&A about the acquisition.

Jaiku’s main goal is to bring people closer together by enabling them to share their activity streams. An activity stream is a log of everyday things as they happen: your status messages, recommendations, events you’re attending, photos you’ve taken – anything you post directly to Jaiku or add using Web feeds. We offer a way to connect with the people you care about by sharing your activities with them on the Web, IM, and SMS – as well as through a slew of cool third-party applications built by other developers using our API.”

Anyways, it’s a micro blogging tool I’ve been trying lately, it’s still closed and I have a few invites, if anyone is interested, mail me.
