Mozilla Labs developers have revealed project Raindrop, an approach to handling a large number of messages from email and RSS to YouTube and Twitter. Raindrop uses a mini web server to dig through messages from those sources and attempts to categorise them, pulling out important or personal messages and bringing them to the top of the user's view. Examples of this filtering include automatically detecting email from mailing lists, messages from friends or relatives or status messages from online retailers such as Amazon, and presenting them in context based on the preferences of the user.
