I see your points. I must admit (and already did earlier) that I also watched the forum for around 2 years before I started posting. So there may indeed be more readers than I thought. However, looking at the Yahoo forum, I got the impression that some people got lost during 2008 who posted in 2006/2007. Has the WOW-virus spread?
Concerning motivation for developers: If I was one, I would be motivated by more finished adventures and more promising demos... and perhaps a nice newsletter!
