it can communicate with hosts that have only IPv6, it can communicate with hosts that are stuck behind a single IPv4 address (if the router acts as a 6to4 gateway) without a NAT being in the way, it can be used to develop and test IPv6 applications without having to build a special-purpose network, it can be used to deploy applications now that already support IPv6 and so are in some sense future-proofed, it can be deployed on either a single host or a network again, trying to judge how well 6to4 works by how well it works with web sites that also support IPv4 is entirely missing the point.
