Hey movix, just saw your question today (haven't figure out at the time how to track my post back).Could the answer to hyyypr help you? it's great you like the design. feel free to ask any specific question, if there's something not clear, I'll do my best to make it a bit clearer. In "one" word, it's an aggregator for sites and blogs as well as podcasts and the feeds are update in nearly realtime, add some social features to it and that's it. A User case could be for a google employee to keep in touch with his company news, it's very easy to do that by checking the google category with all the google blogs listed there, no need to fire up your desktop feedreader all the time, or login somewhere, just go get what you are looking for, and if you miss the news from several days before, click on the "more" option and you can catch up with that stuff and share it to twitter with one click.
