I haven’t surfed much for this, but here’s a person who’s recipe-blogging. Also flickr has a group for recipe/photo combinations. Although I don’t check it often, this recipe newsgroup via googlegroups has cool stuff.
As an aside, I just have to say that google really messed up google groups. Before the interface was elegant and easy to use. My main complaint is that you can’t see more than 10 subject lines on the same page.
