There was a really useful discussion thread on the NTEN list for requests about wiki software and summarized on the blog. I contributed my two cents about wiki adoption off the top of my head and Rob did a great summary of my advice and also from others -- so I'm posting here for the next time I want to think about wiki adoption.
In addition to specific software, there were some general tips and considerations discussed:
- Wikis are good for creating a knowledge base or encyclopedia
- Wordpress or some other CMS might be better suited for a collaborative website project, or Google Apps or Zoho for simple collaboration
- Since wikis are so "free form," a "gardener" or someone dedicated to guiding users and cleaning up may be necessary
- A facilitator may also be useful
- Sandboxes can be used for people to introduce themselves and get used to the wiki
- Wikipatterns has some useful practices as well as some to avoid
- An interesting examination of the "ten best wiki communities"
- More general tips and a case study of wiki adoption
