Pluralsight is one of a few companies in the "education" business that I don't really have high hopes for in general. Pluralsight, Lynda / Linkedinlearn, Udemy, etc. They either target enterprise companies as a way to "skill up" and save money on training. Or they sell to aspirational individuals. But the main problem is that the overall quality is really really low, borderline useless. I haven't seen a site with this model that does better than just buy a book and practice. I think most sites could be beaten by finding good videos on youtube.
I do like Coursera's model, namely because you can come away with a certificate or degree, and the average quality is way higher. Functional Programming by Martin Odersky on Cousera was one of the best online courses I've taken.
