Most active wikis (see the list here) are usually of a unique, non-arbitrary topic that is original and has a lot of traction. Ultimately, there's no guarantee that a wiki will be successful; all the wikis on that list were created just like any other.

You can find pages such as Help:Attracting contributors which can give assistance in regards to making a wiki active.
