I never knew there were 81 wiki platforms. I am hoping you could help me choose one for my needs. I want to make a wiki site where anyone in the world can edit a startup information. Think something like crunchbase. I have a few features planned and need to extend it, preferably in Python. I also want to be able to put a modern looking UI (most wiki's skin is bad, by default). Can you suggest me one ?
