There's a growing number of courses, tutorials, etc online. Does anyone know any mechanism for meeting and collaborating with others who are planning on working through the same courses/tutorials. I am pretty individualistic when it comes to learning, but even I would find collaborative learning helpful at times. Maybe a place to find partners, online or offline "study groups" etc. Maybe meetup.com would be useful, but for some reason I don't see that working. Any recommendations would be appreciated.
