I may love geeking out and working on big complex systems but I also appreciate business simplicity and good content. I have found Scott Allen’s AngularJS courses to be very useful and it turns so do a lot of other people. Scott has found success paring his considerable teaching talent with simple onscreen videos and distributing them on platforms that enable wide on-demand distribution. This is a profitable solo business that does not require running complex propriety stacks – just a laptop, a good microphone and some talent.
