Have you ever contributed to Wikipedia? (Not donation)

[Rockefella]

I usually don't know enough about something to contribute.

Wikipedia management once asked me to write the page defining and exemplifying success. I politely declined though.

Your teacher is stupid. People, students need to be exposed to as many sources of information as possible.The key lies not in the ability to get the 'correct' info, but to be able to process, decipher and think upon receiving all sorts of material.

Bingo.

While using Wiki as a sole source of info isn't that good of an idea, that goes for any source of info. You should always use multiple sources and Wiki is good for this, as all the good pages of info will be fully referenced.

And, something everyone always forgets, is that Wiki is moderated, so you can't just throw up whatever you want.
