What are the differences between a blog and a wiki?

A wiki is similar to a normal web site, but where every page has an edit button, and everyone by default is given permission to press the edit button.

A blog is a web site with mainly a single page, and that page displays individual announcements or "news items" in a latest-news-first order.

A comparison table

Blog Wiki
  • personal, less collaborative. a journal entry or posting is owned by poster
  • can be personal but open to collaboration. a node/topic is considered public space
  • text is considered to be static: once posted, the posting doesn't change (not true, of course, but expected)
  • aim is creation of documents (individual pages as well as the entire wikiweb)
  • monological: typically monologue with audience commentary
  • hypertextual
  • temporal: last in first out
  • a-termporal: nodes change not by time but by way of development
  • captures change in thinking/self/ideas
  • doesn't capture changes in thought/ideas, but creates artefacts of those changes
  • speech: spontaneous, non-revisable and as permanent as memory
  • text: considered, revised, and as permanent as print
  • generally light on cross linking: dominantly sequential
    but

    research blogs and others can create extensive hypertextual webs
    but

    creating internal links is painful and secondary to the text
  • encourages cross linking: dominantly structural, a-temporal
  • links used to connect outside the blog
  • hypertext linking central to text creation
  • knowledge accumulates at the top
  • knowledge is static but contextual: situated - dominantly chronological - but essays are possible
  • knowledge becomes webbed: situated, contextualized
    but

    knowledge is ephemeral: it changes, can be changed
  • immediate: written in the moment, written of the moment
  • mediated: written in the topic, of the topic
