The only other site I actually post on is for gardening questions:
http://forums.gardenweb.com/forums/
There are a huge number of topic areas, each with its own forum, and, as I've found, each with its own distinct personality. The "vegetable" people seem pretty nice and well-informed while the "tomato" folks can get a little strident (my-way-or-the-highway kind of thinking) though they do seem to know a lot (and disagree even more). And the "soil" posters seem to be a combination of friendly, funny, and scary :eek: . I haven't spent much time on the other flower, bush, and tree types of forums I guess because although I love to walk in beautifully landscaped gardens (particularly "English" gardens with lots of tangles and overgrowth), I'm more interested in growing food. Go figure. ;)
GardenWeb is where I go for straight info, but I visit ChefTalk for the wonderful people and the interesting conversations ( as well as the info ).
