Should Colleges and Schools Block WikiPedia

I am still in college and the other day I tried to find some information on google for my presentation paper. I saw cool link to wikipedia and found out that my college is blocking wikipedia.

Do you think wikipedia should be blocked from students in college and high school?

At college we are told that wikipedia is not the source to look for creditable articles, and we “college students” know that, but sometimes you find information on wikipedia that is 100% correct and gives you links to find other creditable resources.

What’s your opinion on that?
