Well, this is unusual: a memetracker that doesn't make your stress levels go through the roof. Unlike the current crop of memetrackers, Cloudee has a calm and relaxing interface, with some nice metaphors thrown in there too - hot topics are "storms" and memes that are bubbling up are called "gathering clouds". From the site:
Cloudee is an automatic aggregator. Think of it like an intelligent RSS reader that culls the daily headlines for hot topics. The hot conversations of the day are tracked using a cloud algorithm based on memes and links. Currently, Cloudee's topics are technology and web oriented. This will later be expanded.
