I respect you a lot and know that you have a lot of stake in the TGP2 movement so naturally you are going to be one of it's biggest supporters but....
I think it's way OVER rated. I have had a TGP2 built for a few weeks and have postponed launching it cuz I just don't see it taking off like it could have. One of the biggest problems is that it's completely saturated with newbies who have made their first site a TGP2. I also keep seeing guys promoting their site as a TGP2 to the surfers... even including the #2 in the name of the site. I've said from the begining that this was a bad move for obvious reasons.
I've also converted a couple hundred of my galls to TGP2 format and submitted them to the pools.. etc... It cracks me up to see the traffic these sites kick out. Some of the listings don't even show up on counters and the bulk of the ones that do are showing 2 or 3 daily hits. The handful of TGP2's that seem to have any traffic are those owned by old school TGPer's who are no doubt feeding these sites with their TGP1's. There just seems to be no real influx of rookie surfers latching on to the movement. It's almost as if it's too late. I wish all of this wasn't true but it's my experience so far.
