This really makes me wish they would leave content up rather than following the cohort model -- there are a handful of classes I'd like to take, but their current model forces users to basically adhere to the university schedule (they have 4x more courses starting in september than any other month). Udacity made the switch after a couple months of trying the cohort model -- hope Coursera considers the same.
I agree. Over the Summer I wanted to do the Python course with my son (9 years old) but it doesn't start until October, when he'll be back at school. Shame. Doing the Learn Python the Hard Way with him instead
Their interface is a lot better and their teachers are great, they've really created a new pedagogy around the new medium rather than adapt existing brick and mortar courses like Coursera and edX is doing. Mind you Coursera and MITx is a great way to get real college classes over the web, but Udacity is rebuilding the whole paradigm and is intensely analyzing data and tweaking to improve things.
