I've been using blinklist for a few months now, and I've really come to value this social bookmarking site very much. It's simple, intuitive and allows you to discover great sites that I would normally never come across.
So I've been using it to keep track on my EVE Online sites. Some of these are corporation or alliances sites, some are for used as reference, some are blogs, while others are news articles related to EVE Online.
All in all, I've got 101 sites so far. And the list keeps getting bigger.
If you know of other sites you use regularly, which are well done, and kept fairly up-to-date, than please let me know, so I can add them to the list.
