Let's just put it this way. Research work using Wikipedia doesn't guarantee you the fast lane to a PhD any more than any other encyclopaedia can. It's reliable enough for most general purposes, but when you need to do much more demanding and pinpoint accurate research you'll have to plunge into seriously deep and specialized academia.
So I agree with Snarky. Wikipedia is awesome that way as a daily tool, or even as a bit more of an intermediary research tool depending on what you're working on.
