I was never on BaM... so, my frame of reference cannot be to that - only to other forums (both guitar/music and others).
There are plenty of forums which offer a faster pace, but that has its own problems. unless you are signed on 24/7 and refresh every hour (or sooner), you are going to miss stuff. I don't like missing things which might interest me, but I also don't want to have to camp out just to stay in the loop.
While others might yearn for 'critical mass', I find that just following even 3 or 4 threads is enough as far as the time I am able to invest. I do read almost everything here, but some discussions are more interesting than others - we all have our preferences.
If it ever got to the point where I was actively following or felt the need to comment in many, many threads, then I'm sure that my personal and professional life would suffer.
I just spent a week away from any computers and I can see that even in this supposedly dead forum I may be reading for a few days to catch up.
Perhaps the solution for those who are bored is to participate in other forums as well...
Your mileage may vary, no preservatives added, not for the other use.
