this isn't so hard to do, you can actually get a feed of all of wikipedia's content, and can re-purpose it to your own site (but you are suppose to give attribution to wikipedia) under the cc license they release it with. did a little research into it, and found it is actually incredibly easy to get the wikipedia content to reuse. :)

Wikipedia releases its content under the GNU Free Documentation License, not Creative Commons. Regardless, yes, any use of Wikipedia content should be attributed.

This is a problem for Wikipedia, and as an administrator I constantly have to deal with people who don't understand even the basics of copyright law or the idea of plagiarism. I have deleted many articles and images that blatantly ignored copyright law. Perhaps I should set this straight:

If you want to use content from Wikipedia, credit us, say the content is GFDL, and link to us - that's about the least that you can do without being a real copyright problem. Wikipedia also has specific instructions for forking (copying) content which can make your use truly legally watertight, even if you use the content in a commercial sense. And by the way, Wikipedia does, via some users, issue takedown notices - saying that our content is yours is still a copyright violation.

If Wikipedia uses your content, ask about it on the talk page of the article in question, or post a report at one of the administrator noticeboards, and someone can help you with the problem - we hate that people add copyrighted material to Wikipedia as much as you might, and we'll delete material if it's a problem.

This article is a classic example of a misunderstanding of Wikipedia - any problems are more that we do not have enough people, enough time, and enough lawyers to fix all of the stealing in either direction that sometimes happens, not that Wikipedia turns a blind eye to the source.
