The lack of understanding the medium of a Wiki, which is very fluid, but not forgetful, is astonishing. They have been around for three or four years, if not longer. It is usually one of the first lessons anybody I have known learns when dealing with a Wiki, they move and when quoting them one must get the version of the information. They are a jumping off point, not destinations. They are true conversations, which have very real etherial qualities.
Is there no sence of research quality? Quoting a Wiki entry without pointing to the revision is like pointing to Time magazine without a date or issue number. Why is there no remedial instruction for using information in a Wiki?
Personally, I love Wikis and they are incredible tools, but one has to understand the boundaries. Wikis are emergent information tools and they are social tools. They are one of the best collaboration tools around, they even work very well for personal uses. But, like anything else it takes understanding on how to use them and use the information in them.
