I don't know if spam-fighting tools for wikis are any better now than
they were back when I tried it (for another topic) but fighting
automated link spam will bring wiki contributors to their knees. Wikis
need to live on servers, require bandwidth, administrators (and most
of all contributors/editors) to become a knowledge repository. They
can begin with enthusiasm and die with neglect just like any other web
entity, including listservs.

Sorry to be a Debbie-Downer, but a dose of realism might be doing
everyone a favor...
