Clean Slate Wiki's

Like me, I'm sure many of you are grateful for the invention of wiki's like wikipedia. Personally, i've been impressed with the way people with previously stubborn bias have been able to become a little more open-minded and forgiving when debating some of the more morally taboo and other 'hot' topics. However, lately I think we're beginning to witness the 'information overload' problem in wikipedia; where ones attention span is stretched so far as to give up halfway through the material, leaving the previously interested viewer with only a portion of the impartial whole. There are four questions that should be asked concerning this problem:

Is there a better term for this phenonmena?
Is it a real problem?
Is it fixable?
How can we fix it?

The above problem represents perhaps the most curious problem associated with user-contributed content, but there are many other less curious (more annoying) problems with the current state of wiki's. Frankly, current wiki's are a mess. Perhaps someone else might like to highlight these problems in more detail.

you could allow people to search entries based on the credentials of the writer of the section or if a credentialed person "OKd" a section.

From my own research on autism (my son is in the spectrum) I could possibly limit the shown data to only those written and/or verified by known researchers/professionals in the field.

Yeah, I guess thats one problem with wiki's; the difficulty of ensuring accuracy.

Is there a site for the clean slate project? Or a wiki? That would be useful.

I've been thinking about having one. Not sure if it would work well at such an early stage though. Perhaps when we get more members?

It might help get more members.
