Dealing with the company that hosts this web site has me contemplating starting a Google Community with a similar theme as this site, maybe expanding it to a region. I'm not really that familiar with the GC but from what I've been seeing, it seems like it could coexist with this site and possibly replace it down the road. It appears to have all the basic stuff you'd want for discussing rides, posting up trips and general chatter and expanding it to a region could be a benefit, I believe. The traffic on this site has been dwindling down to a trickle and GC would be perfect for small volume content. Being under the Google umbrella might be a good thing for users too instead of trying to deal with the peculiarities that forums sometimes have.
Snooping around, I looked for some comparable sites and didn't see anything that wasn't world oriented, very narrow, or designed to pimp products.
I'd like to hear from people that use GC and can explain the negatives to me.
