My first internet site was a "Lois and Clark" discussion group. Shortly after I began posting there, I added myself to a "Due South" discussion group.
Through a series of odd posts, I found myself defending Danny Elfman's original score to the original "Batman" film in the wake of someone who said Elfman's score should have been scrapped in favor of more Prince music.
Sigh.
My response resulted in a private e-mail from a fellow in Canada who directed me toward a discussion group called "filmus-l" where I suddenly found a "home". I posted there for many years, mostly happy ones.
As Bretty knows, there are always a few "floaters" even after you've flushed, and some of these floaters popped up again and again, driving folks away. Filmus-l used to be very active, very thought-provoking and had an international membership. Many folks left. Some broke off and formed a private group with explicit goals of excluding certain "floaters" who fancied themselves the end-all/be-all to the subject of film music discussion.
This group remains active, if a bit unfocussed.
Another great site I found was a messageboard at the Film Score Monthly site. Many friends have been made there (and the main "floater" from filmus-l occasionally poisons the water there, too...but not so much any more).
Additionally, I found myself one day straying onto rec.music.movies (a Yahoo? discussion group, IIRC). It was interesting, even though one poster there named Guttke presumed to "own" the site and passed judgement on every discussion going on. It was there that one Bruce Kimmel encountered me in one of my verabl duels with Guttke and invited me to HainesHisWay.com. This was the day after the 2002 Academy Awards broadcast (for films of 2001).
I've also spent time at the MovieMusicMessageboard but found it to be, on the whole, jejune.
Oh, yes, I found it jejune.
I also joined some theater discussion group...the one where Stephen Newport seemed to malinger 24/7, posting to every thread and commenting on every post. Very tiresome.
So it's HHW.com (in abbreviated lingo) and FSM Messageboard where I hang my hat these days.
