Yes, it definitely is. The only problem is implementing it - that is far
trickier, nearly AI-complete.

Using people as extropy-detectors is of course the best way today. One
way of detecting that at thread is interesting is that many extropic
people participate, so the thread could be weighted by the sum of the
ratings of the participating people, with some scaling for the length of
the thread. Unfortunately it is hard for humans today to distinguish
between a poster and his posts; even when judging the latter judgements
about the first creep in.

There seems to be some instability in such a ratings system: first, a
new thread will just have the score of the originator, so it might be
hard to detect even if it is good. Also, high ranked people become more
visible and have a greater chance of being highly ranked. Here we need
some form of "conscience" in the system that balances the concentration
of ratings.

What we must avoid is having a lot of parameters to tweak. In my
opinion, the best systems are always those that have no free parameters
because they adapt well on their own.
