I haven't heard the tracks yet, but this turned into a very interesting discussion. rab got the point, as it's indeed
The BBs Message Board and everything else is 2ndary. Remember also: every day equals to 5 or more threads, so one cannot chase all the info. If the forum were dedicated solely to the music-makers, so-called "Club of commoners", there'd be a lot more feedback.
I recommend that you hang around, post stuff, listen to other people, and give your thoughts on other people (and you'll see the favor returned).
You've said many fair things here, but I disagree with the highlighted text. There are many examples I witnessed when a newly registered user went straight to this section, posted the link to his work & disappeared, often for a very long time & even completely. 1 recent example - quichenight's cover of I Wanna Pick You Up which got quite enough replies, yet the poster didn't comment on anyone's music. More so, he didn't traditionally thank anyone for the listening. So for once, your theory failed.
