Do you cite Wikipedia as a source on AB?

Yes. I explain my reasons here: http://www.answerbag.com/a_view/2207227

I hate to copy and paste Wiki information into my answers. I prefer to read the information and put it into my own words. I will only cite Wiki as a source if the questioner asks me where I got my info from.

When I use them I do but I rarely ever use them.

Yes. Not because Wikipedia is necessarily an authority on any particular subject, but because they often put things together in a fashion which is easy to understand. Wikipedia also cites their sources, which you can follow up on. And as a last resort, Wikipedia is a good starting point to gather information about which you can do your OWN research to further verify or support what you need. I would never use them as an authoritative source, at least not unless and until they become recognized by other leading authorities as such. And no, fellow bloggers are not 'authorities' in this sense!

Yes I do.. =)

Yep, but obviously not for the opinion-centered questions. It's usually got its own references at the bottom of the page, so further research can be conducted to confirm the information's validity. I have yet to receive any complaints.

On a few occasions I will. Though Wikipedia is still very much in it's infancy, They offer a decent source of information (though not always accurate) on a wide variety of topics. I will also send a Google link for people when I need help making my comments. I'll search their answer and present it to them. SOmetimes an answer is too long to write.

Nah. I've noticed that I generally gravitate towards questions that require an opinion.

Yes, but as much as possible I try to avoid it because some people don't trust it. But in cases where Wikipedia is the only source, or the only understandable source, of course it's the one I cite.
