As a test of a few ideas that had been proposed in various places, and to see what Drupal could do these days, I put together a test site for aggregating science blogs and keeping group collections of important topic-related links. Feel free to browse around the site, read posts and create accounts to rate items.

Groups are owned by their creators, who are responsible for the list of relevant links, but links can be suggested by any member of a group. For more details, please see the full post on Nascent.
