Bring back the wiki?

Are you actually familiar with the old wiki? If you are, and you compare it to the new wiki, I think you'd have to be honest and say that the new wiki is super weak.

It would probably be more helpful to give valid examples of what would allow a wiki to be more useful if it were hosted on codeigniter.com rather than github. The old wiki was shut down shortly after I started using CodeIgniter, but I think the weakness of the wiki on github is due to a lack of use, rather than lack of features.

I understand the basic issue of having some things on github and some on codeigniter.com, but I think those types of issues are easily mitigated (for example, by linking people to the appropriate location).
