Well. I'm not much of a cook, but I took a look at Recipe Source because I never heard of it. I looked at soup recipes and found "The Postman" Italian fish soup which looks pretty good. I liked the availability of browsing and searching, and searching within specific categories.
Food Network has pictures! Yay! And helps you out if you don't know how to spell something and you search on a misspelled term (anadama bread).
These sites demonstrate how community sharing is not really in competition with book publishing. I think people buy more cookbooks than ever, and yet with these web sites it seems like you could really get a recipe for anything you could possibly imagine.
