Mozilla on Thursday introduced Raindrop, a project that seeks to consolidate online communications. The Raindrop team consists of the same people who worked on Mozilla’s Thunderbird, an open source, cross-platform email client. Raindrop will complement Google Wave, the new data communication and collaboration tool from Google. Raindrop employs a mini Web server to fetch users’ conversations from different sources such as email, Twitter, RSS feeds and YouTube and pull out the important parts.
