Raindrop just got released as a Mozilla Labs project!

What is Raindrop?

“Raindrop uses a mini web server to fetch your conversations from different sources (mail, twitter, RSS feeds), intelligently pulls out the important parts, and allows you to interact with them using your favorite modern web browser (Firefox, Safari or Chrome).”

Who built Raindrop?

“Raindrop is a new exploration by the team responsible for Thunderbird to explore new ways to use open Web technologies to create useful, compelling messaging experiences.”

You can read more about Raindrop here, and wiki details along with the weekly call info are at Mozilla Wiki.
