I was kinda of expecting more with a funding, an office, and a semi large team.
I have personally been working with my co-founder with zero funding on a MMORPG social start-up that brings the best features of Facebook to another group of people. We have implemented real-time features through Erlang (including Chat and Streams), data collection/aggregation from games, and far more. (http://www.guildwork.com/blog/ if anyone is interested, its our public testing site, we have not launched). Anyway I guess my point was if 2 people with zero funding and no office can accomplish that, I certainly expected more from them. But to be fair we been killing ourselves slowly by working as hard as we do, maybe they took a relaxing approach. =P
Also for something that is meant to be distributed Rails does not seem like a very good choice.
Just my 2 cents, hopefully open sourcing it will pick things up.
