Personally I don't see it
as overly onerous to have to attend a LUG meeting to be verified.
...it may be fine for you and me, but many people would find it too
onerous. If we wanted to restrict LA membership to people who take the
time to learn how to drive GPG and meet up f2f with a current member
to be verified, then cool, the WoT would solve the identity problem
just like it does for Debian and other groups.
However, I see Linux Australia as an inclusive organisation, not an
exclusive one. Even many geeks think GPG is too hard-core for them: in
a typical LUG only a small percentage will actually have a GPG key and
be integrated into the global WoT. It's not a matter of it being too
hard to work out: most people, even highly technically competent ones,
just aren't interested.
