This is a general question- I want to hear your opinions. What type of forums and communities need a wiki feature enabled?
Followup question - Why should one have a wiki alongside QnA forum?
Do you mean "community wiki" on the posts or a dedicated wiki site?
This "community wiki" is optional (can be disabled), also I'd gladly remove it or make it disabled by default.
Or wiki site will be removed when we transfer all valuable info into static documentation. It turns out that wiki site is hard to keep in sync with the source code, so we've switched to storing documentation in the repository itself.
The wiki site may be useful but for us it does not serve the purpose.
It is indeed very confusing. I can't say I would be sad if the "feature" was dropped in the future. :)

EDIT: I meant a community wiki.
