Wiki's not as bad as people make it out to be. In my field and others, it offers many excellent articles, written by educated professionals.
Moreover unlike many other sites, Wiki articles can be corrected by people who know what they're talking about. If you find an error elsewhere, you can notify the site owner, but there's no guarantee it will be fixed.
Finally, while I don't accept Wiki article as sources in my classes, they do give student references and external bibliography that they can find in libraries and read for themselves.
Original research is a GOOD thing, dear. That's what scholars do. It's something that should be encouraged.
