The forum ebbs and flows. There is a lot of competition out there these days- last count at least five other English speaking forums, with as many foreign language sites, plus social networking groups on Facebook etc.
A lot of newcomers coming into this hobby are looking to see what they can take out, rather than what they might contribute- the current zeitgeist perhaps?
There are exceptions to this, but not sufficient to maintain the kind of dynamic exchange of ideas members may have seen in earlier years. It's not fair or reasonable to expect the same few individuals to keep on providing the entertainment.
Adding more sections to this site is just going to add to the confusion, as it looks too cluttered already.
For me the 'General' forums are the ones that have real relevance, the others are with the odd exception largely superfluous.
