I always liked the idea of the keyword searching, but it has a fatal
flaw:  the people writing the articles aren't qualified to write the
keywords.  It may be possible to get a pretty high quality filter
(better than choosing groups anyway) by having software guess at the
keywords based on the contents of the article.  It might be a fun thing
to prototype.  Threads and message chains are more accurately modeled as
DAG's than as hierarchies (and I wish the news readers supported that!).
