Mozilla’s labs group have released some information on a messaging solution codenamed Raindrop. It runs on CouchDb, and seems vaguely related to the whole APML (attention profiling markup language) movement – allowing users to sift through the daily dump of information by applying qualitative filters to info. (e.g. emails from my family are more important to me than Tweets from some celebrity I happen to follow – that sort of thing).
I don’t really have an opinion on it as yet, but given how much I dislike email, and how disappointed I am with Wave, it’s good to see life in this area.
