The blog

1
The blog even my dog has one!

• Blogs typically personal, spontaneous, static
  and chronological.
• A blogger will post something an opinion, a
  journal, a link and others will comment and
  opine.
• Blogs serve as a good way to capture what is
  happening at the moment like a working memory.
• Issues are not necessarily updated after they
  happen, unless the blogger links back to them.
• They are searchable, if the blogger attaches key
  words to their posts.
• All links tend to be outside the blog.

Wikis It must be true, I saw it on wikipedia

• Wikis are more like a collective and
  collaborative space, where groups of people will
  add information and knowledge in a repository.
• Wikis can serve as reference places for groups
  who are trying to capture information and
  updating it as necessary. They are editable by
  groups of people, versus a blog where edits may
  be limited to one person or a selected team.
• Unlike blogs, Wikis create whole documents and
  wikiwebs instead of individual posts on subjects,
  thus creating a web of knowledge.
• Since wikis are spaces of collaboration, they are
  mediated or moderated, which is not the case in
  blogs.

Whose using what at NOAA?- a brief sampling

• ORR/Hazmat uses Trac, which gives them a common
  place to put documents, code, summaries of
  meetings serves like a wiki, but is more like
  project management software
• NOS-CSC uses JIRA/Sharepoint for forums and
  collaboration. According to their developers
  blogs are great for things like meetings or large
  conferences to update information to people at
  the office.
• NGDC used wikis for corporate knowledge and
  blogs for individual work logs including notes,
  discoveries and problems. NGDC has a wiki on
  their public page for metadata resources.
