I agree on that point, however many schools and universities do not allow Wikipedia to be used as a form of reference
I understand that but i hope you do realise you're on a forum right

? I'm not going to spend a couple hours writing up a fully referenced paper when wikipedia provides a fine summary for the general audience here about the information i want to present.
I think on errors and bias, on the major articles on things you'd find in most encylopedias, wikipedia is on par, if not better with the media. Ever watched british or american news? Or God forbid..press tv?
If you haven't go watch them for a while and come back to wikipedia. You'll appreciate the difference.
