privacy features of the old Blue Dot. However, they've added a new method of finding trusted links that doesn't require building yet another social network. The new site adds a topic network that does a lot of the networking and recommending implicitly along with an easy-to-use feed reader for sorting through new links. It's kind of like Digg and Delicious combined with Google Reader.

Users can annotate their links as well as see multimedia previews in order to better understand what they are looking at. The bookmarking system works similarly to Delicious. Users place a bookmarking button on their browser and click on it to mark and then annotate a page. The new topic network helps users discover links without resorting to finding trustworthy individuals.
