Wiki -- have we gone the wrong way?

It has been a while since a wiki was the center of attention. Perhaps it was the installation process that made it too complicated. Or maybe it was the lack of security.

I just ran across dokuwiki, an implementation of a wiki that uses text files rather than a database. Installation is very easy, as is shown in the 2 minute video found here.

I also saw a very good departmental website that is based on a wiki. That got me thinking.

What if we had much of the Botany Department web site built using a wiki? Would it solve any problems? Would the look and feel work?
