Ask these questions about wikis you consider
using for research:
What is the purpose of the collaborative project
and who began it?
How rich is the wiki? How many pages does
it contain?
How many people appear to be involved in editing
the wiki? Does it seem that the information is improved by
having a variety of participants? How heavily edited are the
pages you plan to use?
Does the project appear to
be alive? Are participants continuing to edit it?
Does the information appear
to be accurate? Can you validate it? Can you use
other sources to triangulate the information?
