Well, I am using september gnus.
I would be interested in your observations on how the GroupLens
predictions match up against the scores you get from the gnus score
files.
Right now, I think the nicest feature of GroupLens gnus is that I can
read groups using the ',' key to take me to the next highest scored
article.
What I would like to figure out how to do is adjust the scoring somehow
so I can expunge the articles with low predictions < 2 in rec.humor for
example, and see the articles with high predictions plus I'd like to see
all of the articles for which I have no prediction. The trouble is that
my default score is 0. Is there any way to tell the expunger to throw
out articles below the expunge threshold unless (= score default-score)?

As soon as we figure out how to calculate some confidence numbers that
are meaningful. :-) So far, most of my efforts have been spent on just
getting the whole BBB system stabilized (we seem to be there now). Over
the next few weeks I plan on spending a lot of time working on and
analyzing the algorithms.
We've collected a LOT of ratings 30,000+ over the last six weeks, so
I've got some good data to work with in trying to improve the current
prediction algorithms, and hopefully get some confidence numbers.
