Wikihosting

What wiki hosting site you reccomend?
(i'm planning to migrate from reddit wiki, don't need anything fancy: just page history,categories(or tags) and hyperlinks).

It would be very cheap to host a text-only version of reddit.
It would be somewhat expensive to host images i.redd.it
to host videos on the 7th largest site will bankrupt them,
Even youtube isn't profitable. Online video is incredibly expensive:
both latency and bandwidth costs become astronomical for popular content.
They won't start such an expensive function just to please users:
they intend it to be showcased feature to investors and important selling point
(we got "profile posts", "image and video uploads", we can compete with facebook and youtube)
