Imagine a Web site that has over 4,000 links to sites of interest to Linux enthusiasts. Forget about dead links, because this site would be vigilantly maintained by a small group of people totally committed to the work of providing useful content. Instead, expect fresh links several times a week with handy accessories like quick links to related pages.

Found this to be dead handy.
