That was in the old system. Probably what's holding them back is just coming up with a comprehensive, scalable design, rather than adding boards willy-nilly. I'm guessing we'll see something to address this in the next version.
Actually, that's not correct. Jacquilynne addresses the issue here, and there are still technical issues (not the same technical issues as before, but technical issues nonetheless): http://www.chowhound.com/topics/39709...
I'm in the general Sacramento area, but I doubt Chowhound gets enough traffic about Sacramento to warrant another board. OTOH, I think if SAN DIEGO had a separate board, things would tighten up for both San Diego AND us Sacramento-area types.
I agree about the amount of traffic it seems like the same places and areas of town get recommended over and over again. OTOH, since CH signed on with CNET I have noticed a little more interest in the general area which is really refreshing.
