Wikipedia's Credibility

I do consider Wikipedia to be a credible website for research. I've used it before on many a paper or research project while I've been in college. Some professors say not to use it, others don't mind if you use it, and some encourage that you use it. Big deal if it is a user-edited website. It's not like the stuff that people upload on it is bologna. You can find credible information. By looking at wikipedia's five pillars for posting something on the website, it shows to me the fact that you need to have credible information. Otherwise it's not going to stay up on the site. They have to meet certain guidelines so..... All in all, Wikipedia is ok by me.
