There's also obviously SAGE, which does a much better job, but is
focussed on systems administration in general, which I look at as more
of a necessary evil than something interesting :) AIUI, they have a
regular meeting on a weeknight that consists of a talk and some food,
and that's pretty much it.
If we want a "professional community", does it make sense to have one
that brings together Linux-friendly management types as well as hackers,
and if so, what sort of talks do you have then? Or what's you excuse
for a get together?
