If Twitter and all its buzz in the web community can be considered its own growing world of sorts, then Leo Laporte - one of the service's foremost users according to Twitterholic - just sent ripples through its oceans by announcing his decision to move to Jaiku, a similar service that seems to have longer legs and quite a few more features. Since this was the first we've heard about Jaiku, we couldn't resist swinging by to sign up for an account to see what this micro-blogging, über-status message service has to offer.

In a nutshell: a lot. For starters, Jaiku acts as more of an 'online presence,' allowing you to do things like import RSS feeds from any of your other web properties (including photo feeds from the likes of Flickr) in addition to its fundamental feature of allowing you to post 140-character, SMS-friendly updates of what you're thinking or doing. Jaiku also has refreshing bits of genius sprinkled everywhere, such as the ability to group update notifications via email instead of sending single notices every time any contact posts something. On the downside, however, Jaiku doesn't seem to have nearly as much of a 3rd party following. It has no API (yet), so we're having a hard time finding Jaiku equivalents for TriQQr and the Iconfactory's spectacular Twitterrific client, let alone all the widgets, plugins and mashups which Twitter has quickly grown a reputation for.

Still, Jaiku offers plent of micro-blogging goodness, so give it a spin if Twitter simply isn't offering enough meat to sink your free time into.
