But in all reality, I don't think I'm looking in a sentiment/semantic 
analysis approach... the technology (and research!) here is too limited 
to be of use, imo, and the "misses" are not as easy to fix as in a 
community based solution.

The misses are also really ugly, imo... unlike a Google search where you 
know that the algorithm may be "gamed", "gaming" a system like this just 
looks amateurish and ineffectual -- no matter how good the underlying 
technology is, it doesn't play well to the end user.

Bayes' integration is a great idea for filtering out spam before it hits 
the database, or even after, since spammers are generally really bad at 
changing up their posts.

I think that computers simply aren't as good as people at doing real 
time sentiment analysis, although Google may be able to do something 
with it with all of the data that they have access to.

I'm looking for a technology solution that harnesses the inherent 
intelligence of the users of the site, but in a manner that relies 
solely on the users' interactions, not on the content of the 
submissions, especially since (and here's a wrinkle I likely should have 
mentioned earlier) -- some of these comments may not be in English (the 
plan is to be international)!

Congrats to your cousin, though... Google is surely a nice place to be 
to explore this type of thing.
