Thanks for the input. Some of those are already listed, but I'll input the rest this weekend.
For those that don't know, dmoz.org is the site of the Open Directory Project. It is an "open source" initiative to create a human-edited catalog of the best of the Internet. It was started by Netscape in the late 1990's, and has become the world's largest human edited directory of the Internet.
Thanks for the sites, and keep 'em coming.
