I have to agree with Korm, on my site, for example I give factual information, I give MY opinions, and I accept comments. I’m in control.
On a Wiki site, you will need an “approving body” to filter the inputs, and also have to in a way verify the correctness of the information.
For some reason, often what should be factual exchanges of information giving which way is “better”, degrade into name calling, innuendos, slander, etc.
So your “approving body” will have to be more than one person, and who is going to monitor and manage that? Even Wikipedia is full of, well, to be honest… crap… many things there are not correct, and often what succeeds is persistence rather than accuracy…
It’s a noble and lofty goal, but a lot of overhead.
We have a great forum, where stuff can be discussed. You can search the forum with Google to find threads on great discussions. Reading the threads will give people information and varying viewpoints. That way they will know track power is better! (ha ha)… seriously, personally, I don’t have the extra bandwidth to contribute to another “authority”…
