Twitter doesn't have a grouping feature yet (even though they said 7 months ago it was "at the top of their list") but that hasn't stopped a group of open source aficionados from finding a way to form one anyway. Five Twitterers including SourceForge's Ross Turk and open source analyst extraordinaire Raven Zachary launched The Pulse of Open Source today, calling it a "collective stream of consciousness from the open source community." We just call it "cool."

All you need to do is bookmark and visit the site, or add it to your feed reader. As people the site follows update their Twitter feeds during the day, their tweets appear on the site or in your reader. The site follows a wide assortment of open source community members ranging from CEOs of companies like MindTouch, to community managers of projects like OpenSUSE and Hyperic.

The tweets don't always focus on open source, but we like that because otherwise the site wouldn't be as much fun. How else would we know how Zachary got those cool glasses?
