Hive is already my main content platform. I have been bitten too many times by companies shutting down social sites (Google+, Multiply, Tsu) or I wiped my account (Twtr). All that content is gone from the web. I do have backups of some of them, but not sure what I'd do with it.
Hive would be pretty hard to shut down and that was part of the attraction for me. The rewards were a factor too of course. If we ever get an off-world colony then we need a node there.
