I think people have been told by too many teachers that they're not allowed to use wikipedia as a source, and therefor they seem to associate that with wikipedia being a bad source of information, WHICH IT ISN'T.
It's one of the best you'll find. It's one of the best starting places for any kind of research and has a plethora of sourced information. You just can't use wikipedia itself as a cited source. That's it. That doesn't mean it's a bad place for information.
