Here are a few things to keep in mind as well - and from a member who has been here for about ten years:
1) Steven has been posting a bit more in the past 2 1/2 years than previously, if that's any consolation. Keep in mind that for a fair bit of time he was also touring the planet picking up recipes for Planet Barbecue, starting up Primal Grill, and so on so he's busy.
2) The board is always quiet from the week after Thanksgiving to mid-April every year without exception. It's a seasonal board, for the most part and it always picks up in the spring. This year will likely be the same.
3) This board goes through phases all the time. First it was competition BBQ, then WSMs, then CharGrillers, then Kingsford issues, then Ugly Drum Smokers (UDS) and a lot of others. Now it's BGE-mania and "Click here to see the full post on my blog". That last one is a bit troubling as it draws members away from the board. A lot of those other sites won't even allow members to post URLs inb their signatures, let alone post blog links.
The point here is that trends and members come and go but the board is still here. Even with the Egg-heavy blog posts, we still get a fair bit more variety in grilling season.
Oh - and check out Steven's show Primal Grill - he's used everything from Weber Summit and kettle grills to BGEs, hibachis, UDS rigs and offset smokers - and this board reflects that. Steven was on the BGE bandwagon before there was one.
4) A bit more about BGEs: yes, it's a good unit but we've got owners of CharGriller, Weber, Broil King, Napoleon, and scads of other grills here, including CharGriller and other kamado-style cooker users. And yes, I've sensed a bit of "BGE snobbery" in some posts - sorry - but it's there sometimes!
I have to admit, though, that I sometimes just skim these posts without replying too.
Old Smoker - The only way I can see around that is for the other non-BGE members to post more. Once again, I think things will change in spring. Heck - maybe some other newfangled grill will become all the rage and then we'll have a whole bunch of new posts about it instead.
For that matter, my BioLite camping stove has a grill attachment. Maybe that might get popular this year. http://www.biolitestove.com/
5) Just a little note: the number of posts any member has doesn't reflect the amount of time any member has spent on the board. We have loyal members who've been here for 10 years who haven't posted regularly or often. They're just as welcome as anyone else and certainly aren't part of any "lurker problem".
6) As for a general "shoot the breeze" section, I don't recommend it. I've seen similar sections on other BBQ sites and they've either degenerated into off-color jokes and political rants, or interest in them just disappears once the novelty wears off. PMs work just as well.
And this being the Barbecue Bible site, I don't know if a non-grill section would fly at all. However, I've seen a ton of non-grill-related posts on this board (usually with OT in the subject), and no one's ever really raised as stink so so there's no problem with posting these to the General Discussion board.
7) Keep in mind what ScreamingChicken mentioned above - BBQing isn't necessarily as popular as it was a few years ago, and a lot of members have moved on. But once again, things may pick up in summer.
Personally, I don't post the 40-60 times a week as I used to either. This is in part because I've switched to a new job in summer of 2012 and I've been running a small business on the side since 2009 so my time is a bit more scarce. It's also in part because this has been a really long winter and I've still got spots in my yard under 2 1/2 feet of snow. The first time I grilled this year was yesterday (pork steaks) and it was still nasty enough outside that i didn't want to bring out my camera.
But once again, things may change this spring.
