There has been some discussion lately about what we (Wikipedia Review) are "really" trying to do. One thing that confuses some people coming here is that we actually disagree with each other. Some of us think that some things are big issues, while others disagree. But what do you see as the biggest problems with Wikipedia? If you were going to write an accurate "Criticism of Wikipedia" article, what kinds of things would you include?

I'd like to get an overall kind of view as to what people think are the main problems.

Furthermore, if you want to, you can give examples, links, and even an explanation as to why each problem is the most serious.
