I&#x27;ve used quite a few other (pay) MOOC services; subscription based, pay by class, free, etc...<p>Pluralsight, Udemy, Lynda, Coursera, Code School, Stack Skills<p>I&#x27;ve also used some small independent ones as well (Bitfountain is just one example).<p>The thing I would be really curious to see (but unfortunately don&#x27;t think we will see any time soon) is how the profit numbers stack up on these different pay models.<p>For the subscription based services I will pay a monthly fee for no more than one service at a time and I will make heavy use of it during that time period.  This is what I did with Pluralsight, Code School, and Lynda.  Got a subscription and used it for awhile then canceled when I was done with the material I was interested in or I didn&#x27;t have enough time to spend for it to be worth the money.<p>I also cap the value at about $50&#x2F;month max.  Not that Udacity has bad content, but there is great content on the competitors too.  I can sign up for Pluralsight + Lynda + Code School every month and still have money left over to buy some courses outright on Udemy or Stack Skills.<p>In total I&#x27;ve spent a lot more money on buying courses outright from sources like Udemy.  Originally I was looking there for some specific technical classes, but they have so much variety I have spent more money on things like art, photography, and design classes.<p>Wow... I went off on a bit of a tangent there.  Anyway; really would be interested in seeing how much money is being made by these different services as well as seeing percentages&#x2F;dollars of how much of that passes through to individual content creators etc...
