Well, I ran across a very interesting website the other day: http://www.miningco.com/. It’s somewhat like Yahoo!, except that every category has an identified (human) guide to pick and choose the links there. Even better, every guide puts up articles within their category, about the state of that hobby/industry/whatever, techniques for improving oneself within that category, and so forth. Wonderful informational resource. My only complaint is how busy the pages themselves are; too many buttons and banners and such for my tastes.
