I love the folks at Togetherville. They are the "facebook for kids". Mandeep Dhillon and the team are passionate about a safe, fun environment for kids to engage with one another.
Here's a great opportunity! How about joining their team as an interaction designer? If you want to be part of changing the social landscape for the web, here is a place you can do it (and have fun in the process).
Don't believe me? Earlier in the year when Togetherville needed to rethink a lot of the social interaction I suggested Tangible-UX as a great partner. They got involved and it has been one of their favorite projects.
