WIKIs and Truthiness

Are WIKIs the new PowerPoints? The plain vanilla, Travelling Pants, (you don't really believe that one size fits all, do you?), darling of Web 2.0ers everywhere?

My objections to WIKIs:

1. They're dull. I see one and my eyelids start to droop. I understand the advantages of not having to know how to design web pages, but I would like to see a little creativity in the layout.
2. Truthiness. I am still leery of the way content can be changed. The way I look at it, each edit by a new author ought to link to a new page. I do admit that many of our current electronic licensed databases are far from error free. (Compare the different Gale biography articles for a musician and see how many errors you can spot.) However, my feeling is that if WIKIs are the written equivalent of talk radio they are to be taken with a Grain of Salt...
3. Why are so many out of date? The advantage to WIKIs is that they are so easy to update, the perfect collegial, collaborative tool. If so, why are so many out of date, orphans of the web? If it's everybody's job, could it turn out that it's really everybody else's job?

I did enjoy WIKIs in Plain English and think that for a collabortive project with a firm deadline and timeline, WIKIs could work well. Maybe a WIKI-Blog hybrid might be an answer for something like our strategic plan.
