Ive used it alot of times, like when my partner was telling my about pyramids mars layed out the same as in Egypt (WTF) i used the Wiki to see to if he was telling the truth, cos he often tells me crap, so i use the Wiki to check up on it. Or sometimes when im bored i type in random crap and see what i get lol, the only problems i ever have, is if i want info on something and i don't know how exactly what its called or how to phrase it, then i get given load of stuff i don't need, but that's the only thing i have trouble with other than that it seems pretty muck OK
