Discussion Forums are TOPIC centred.

  • discussions are organised into topics by 'threads'
  • anyone in the community can start a thread on a topic of their choosing
  • all participants have an equal voice
  • posts require someone to reply for a discussion to take place
  • you can follow through a thread on a particular topic

Blogs are AUTHOR centred.

  • posts are made by the blog's author only (may be a group)
  • posts are usually opinion pieces and written in the authors voice
  • readers can add comments to the author's post
  • organised in reverse chronological order so the most recent posts show on the entry page
  • reflect the authors identity in the tone, look and feel and content

Wikis are CONTENT/DOCUMENT centred.

  • editable website with a complete version history kept
