Active Ruby On Rails (Web2.0) sites within the country

Soopie and Iease are sites that I wanted to introduce several weeks ago, but I've been busy with the release of the Hamster open-source project, so it's been delayed until now. All three sites are in Beijing, and the development teams from Soopie and Iease will be attending next week's RailsBeijingCON. I'm looking forward to learning more about the developers' thoughts and the websites' concepts during the face-to-face exchanges with their development teams.
