Wonderful world of Wikis

What I am finding with a lot of the Web 2.0 applications that there are quite a few that aren't being visited or commented upon. I think the trick to this is to create and engaging and rellevant, blog, Wiki or RSS feed something that is of interest and benefit to our customers.

One idea I had for a Wiki is to have our users comment on our resources. This may be especially useful for online resources, particularly what the customers find useful and what they don't.
