Let me take a stab at this from my perspective.
Although I don't post very much, it's only because I'm busy "behind-the-scenes" as it were trying to find/acquire new sites for feeds. Trust me - it isn't easy. Though I can completely understand your disappointment that there aren't more Centers being fed, I can tell you without any doubt that it isn't because thats not what the community is interested in.
And it is just that, a community.
I think one of the reasons that more centers aren't being fed is due in part to the way the transmitters are placed. Many people that are willing to feed know that they are capable of sending XYZ airport because it's right down the street. Very few people know that the ZYX remote communications outlet is right down the street, and so they don't write in. If more people knew, perhaps we would be better able to recruit ARTCC feeders.
I have a fairly accurate list of all the ARTCC RCAGs, but don't have the resources right now to prune it down and publish it somehow. What would be great would be to generate a Google Earth interface that we could direct potential feeders to. Is that something you might be interested in helping with?
With regard to cliques and the witholding of technical information, I'm sorry that it seems that way. Please be more specific about those instances, either here or in a private message to me, and I'll work to try and alleviate that. For technical issues of any type I encourage people to either e-mail me directly, or send an e-mail to the site technical address: tech@liveatc.net
Concerning quality of sites, I can address this directly. So much of what happens "in the back room" doesn't get seen, and that probably leads to some of this uncertainty. There is always a lot of interest in becoming a potential feed site, but not every one of those interested sites ends up making it to the front page. The feeds are screened first to insure that they are of the highest quality that LiveATC folks have come to expect.
Your views are important, and with the flurry of activity and interest of late, its hard to keep a strict balance on everything. Of course many of us have careers and families, and it's always difficult to juggle them all. My views are, of course, my own, and I don't speak for Dave. Nonetheless, if there's something really bugging you, let me know and I'll do whatever I can to work through it for you.
NYARTCCFAN, and others - What are the top 3 or 4 things you'd like to see changed/improved?
