it wouldn't surprise me if wikipedia did this, and they should. there are some things on the internet that i have no problem going on and trying to sneak a little advertisement in here and there, but i view wikipedia a little bit differently. there has been a lot of work put into it from people all over who aren't looking for anything in return. it's crossed my mind once or twice to go add my link to the bottom of something relevant but i won't just because ive got a lot of respect for the site. i don't think wikipedia even generates any money besides donations, does it? ive never seen any advertisements or anything on there, i cuold be wrong though.
