The HPFGU difference

[lunalovegoodrules]

These groups require that people format their posts as whole answers,
not as single points at the end of a series of nested attributions, as
a policy to encourage people to compose, to think about their posts as
items in themselves, not as some part of a generalized, internet chat
or usenet "noise". There is no law that all internet groups need to
use identical rules.

This is the whole point - and it works. When people can't get past
their automatic responses, can't join in on the terms explicitly
stated in the introductory emails the group sends out, they waste a
lot of time trying to make completely irrelevant, obstinate, childish
points.
