I live in a community that has FTTH and its great!
We live in Issaquah Washington a suburb of Seattle and the operator just upped our speeds to 1Gbps for $199. There is about 3000 of us with service and I find it awesome. We can also get 100Mb for $55 which is a steal in our area. Comcast isn't even close. The operator, Highlands Fiber Network, is the community and did it all without government monies. They been doing it for over 10 years. Not sure what is in Chattanooga but I can't recommend more getting FTTH out to everyone in the U.S.
