An extensive and well-written overview of wikis can be found on this blog Group Presentation: Wikis. Here’s an excerpt mentioning Confluence, but the rest of the article is worth a read-through as it covers many topics related to wikis in a tone that’s easy to understand.

Some things to consider when choosing a locally installed wiki:

  • Ease of installation
  • Ability to customize skins/templates available
  • Programming language with which it’s developed (PHP, Perl, etc)
  • Data storage system it uses (Database, file system, revision control system)
  • Availability of documentation and ongoing development support
  • WYSIWYG versus mark up language editing
  • Cost (there’s plenty of open source wiki software out there, but some that you pay for (commercial software) such as Confluence)
