The problem remains of how to retain this flow of information to grow
a useful resource for learners. This is the idea that occurs to me
now: What if we had a dedicated mailing list, entitled "gimsnu", for
discussing the meanings of gismu? You could search the archives of
that list for a gismu in order to learn more about its meaning, and
the results would be likely to be useful because they're part of the
gimsnu.
I agree with a previous poster (lojbab?) that such a discussion belongs on the wiki. mu'o mi'e komfo,amonan
