If you like lists then this site might be of interest to you. It has a posting about genealogy links, mainly US, and they seem to have covered most of the more popular ones with a few more thrown in for good measure :) http://www.accreditedonlinecolleges.com/blog/2010/50-places-to-find-your-family-history-online/
Scroll down past Thinkers to May 27th and watch out for this -
"Are you interested in learning about the history of your family? You can find out a whole lot just by searching online. Here, we’ll take a look at 50 of the best resources for genealogy research on the Internet."
They have it nicely split up into categories - general, search, family facts, communities & tools, BM&D, and data & archives.
I dare you NOT to take a look at some of the other lists e.g. Beating Writers Block and Really Cool Bookstore Blogs :) Interesting.
