Same here :/ It seems that IPv6 is a mere afterthought for most content providers - like Linux ports for popular Games... or civil discussion on forums. ;)

The weirdest thing I noticed in the past was, that IPv6 via Tunnelbroker.net actually worked better than ISP-provided-native-v6, though I haven't tried using a tunnel in a long time.

A lot of websites that resolved to AAAA didn't have a working server on the other side.

Sounds more like a problem with your ISP's IPv6 support than the content providers. It seems unlikely that someone would go to the trouble to add an IPv6 address to DNS if they didn't have a working server up. It's much more likely that crappy ISPs don't have their IPv6 infrastructure set up correctly.
