Looks great... but... Ruby on Rails, PostgreSQL, Redis 2.6+ It's like you want *NO-ONE* to use it. Rails is still niche and not supported by many (quality) hosts. PostgreSQL is limited, but at least more available, and Redis? Well unless you're running your own box that's not likely to happen. Until it's as easy to install as something like PHPBB this will be a niche thing that people will say "Cool, wish it worked on my box but it doesn't so I guess I'll use X". Until it works on a hosting company solution which is what 99% of forums use it is pointless. Which is a shame, because it looks cool. Maybe someone will fork it and make it useful to the rest of the world.
