Let's get back to topic, shall we?
If the commercial section is a no-comments thread, why have a thread? To save on development costs? To make it look like a normal topic not an ad? I kinda feel happier if it is a clear advertisement, not a topic to not comment on.
A discussion would be far more informative in general if one could actually look at the technology presented in the ad and discuss that... i know a previous attempt at this went awry a bit... but we can probably work out the details. Practically though there are some people who would prolly have difficulty not taking the mickey out of an ad-thread.

I also have heard that the general public does not like to hear any counter arguments to the latest and greatest, but are we the general public then? Will such an ad then be aimed at the "correct" audience if placed here? I'm assuming not all AV shoppers in the country post and read here, so what point would advertising that does not aim at the participants have. In fact if one could have these discussions and not become an ad space, I am sure a lot of people would actually care more for this type of interactive advertisement, as interaction is the nature of a forum, not just an ad-space. It would probably lead to many more people browsing the forum as it offers something different to run of the mill.
Looked to the PMF site and in the first few trade discussion threads I read, I came up against what I'm hoping us sefricans can avoid... And for the rest the trade forums a bit quiet...
