We use Google site's wiki to host a large portion of our internal documents. We use it to track releases, ideas, brainstorms, lists, rack/asset info, etc...
We've realized this is not ideal and we've started hitting capacity/bandwidth limits and we're not really ready to get a full Google apps enterprise setup. We're also very disappointed in Google for not having an export feature for site's wiki, but that's another issue...
I am mainly concerned with finding a replacement with a similar ease of use and the ability to run off of CentOS.
I've seen other articles on Serverfault mention Confluence and Mind Touch. Does anyone have any experience with these or suggest others?
Thanks.
