I never figured out exactly what the broken scenarios were nor did I
try to figure out which gateway was causing them.

Ignoring Google Groups, there are 9 possible combinations:

   Usenet <---[gateway]---> M-List <---[gateway]---> Gmane

 1. Usenet followup to M-List posting
 2. Usenet followup to Gmane posting
 3. Usenet followup to Usenet posting
 4. M-List followup to Usenet posting
 5. M-List followup to Gmane posting
 6. M-List followup to M-List posting
 7. Gmane  followup to Usenet posting
 8. Gmane  followup to M-List posting
 9. Gmane  followup to Gmane posting

Most of the combinations seem to work most of the time.  It looked
like there was at least 1 broken scenario when subscribed either via
Gmane or via "real" Usenet, but it's pretty difficult to glean the the
signal from the noise created by people with broken MUAs and/or NNTP

It's actually pretty impressive it all works as well as it does...

In any case, ignoring all postings from Google Groups is recommended.
