Yeah, a lot of experienced coders will say this is not where coding really happens. Say that you want to see someone's work flow in Emacs or how to make a python/django (web framework) website for the first time. This bridges a lot of gaps in knowledge and experience. If I could have simply seen which editors people were using and how they switched between coding and testing and revising, it would have saved me many hours of trial and error. Now, of course, actual "coding" meaning the design and the implementation happen in your mind, but that doesn't mean this isn't a wonderful learning tool. Although, I do find it really funny that they stream the music people are listening to. Sure, maybe it boils down to watching other people google the same stuff I would, but I still think that in the field of coal you'll find a few diamonds in the rough. This might even be a good tool for psychologists because we can clearly see the ability to concentrate on a given task with the omnipresence of the web.
