All right, that is really good news. Now, besides Google with its ipv6.google.com, and all the rest of the services enabled for v6 on request from ISP (http://www.google.com/intl/en/ipv6/) we have facebook going IPv6. This is huge, as facebook is known to be one of the largest social networks out there, raising the standards for the rest of the content providers. Thanks Facebook for the effort!!!
