I was reading the following article on TechCrunch http://techcrunch.com/2011/08/22/codecademy-surges-to-200000-users-2-1-million-lessons-completed-in-72-hours/
I have been looking at tools to assess the quality of potential new employees so this caught my eye although not suitable for me I think it is a great idea. It has foursquare type achievement badges so you can get “social” and learn with your friends.
It clearly is getting popular with TechCrunch reporting 2.1 million lessons completed in 72 hours and with a recent investment of $4 million.
I am intrigued to see what their business model going forward will be, it looks like they are going for the freemium model with the current offering being free and maybe charging for specific lessons. If they want to do more advanced assessments to screen more experienced developers that would be great.
