I created http://www.Learneroo.com to teach programming and more through interactive content and challenges. I'm looking for more developers to help with:

a) running code online b) creating interactive javascript "explainers" c) connecting students with tutors or jobs

I'm also interested in joining another startup doing one of these things, and just created a site for that purpose: http://startupmerge.com/.

Please contact me at ak[at]learneroo.com to find out more.

I'm also looking to help people learn programming, either Java or Ruby.
