Jon this board is a fan community and has only been going about 5 months. In regards to your points though I know that with the release of the patch that activity is at a peak and unfortunately it seems to be those who have problems who are the most vocal and that's quite understandable, as the wait hasn't been worth it to them and this is why we are asking for your feedback. At the moment all the feedback (as well as general hate) is going on at Atari's official boards and why not as they are the source and as I said we are just mainly a community who enjoy this game.
In regards to your second point, with a board like this most of the conversation is going to be about the game, games, cars and usually anything related to cars. Of course the General chat section encourages off-topic conversation and there are clear examples of this going on but as I said we are mainly small right now compared to what you would call an active community.
The third point I can't say much about as I don't really play games on my PC being as it is my workstation, though that's not too say I haven't seen the attention and respect that it appears not to be given to the PC crowd. As a mod at the Atari Europe board I see some of the behind the scenes talk and such and I can tell you it's more active than you think, there's just so many departments, quality control and testing (you may laugh but it's true) but unfortunately inevitably there's always an issue with something. I'm not excusing what's been happening but I have seen that it's not the "sit on your hands and wait" or "lazy workers/developers/coders" approach that most people seem to have of Atari and Eden Games.
Now please let's keep this on topic, if the game has problems for you or is now running please post a description and of course your specifications, anything that can make this game improve and work better for more people and configurations would be great, as even if you don't like to admit it, this game is good, it just unfortunately has some serious issues for some.
Thanks.
