Bad news: Opera lost IPv6 ability in version 10.10. Opera cannot connect to this site, even if it's running on a host with IPv6 ability.
No news: The search engines still don't support IPv6. The (other) browsers still support IPv6.
Good news: Today I saw a torrent swarm with more than 20% IPv6 peers. Not a special swarm in any way: I download my old LPs whenever I play them, so I'll be able to play them in the kitchen or office too next time. It was the torrent swarm for one of them.
