Good article, Steve. Here's my $0.02 worth. I think adopting new technologies is more than whether or not you can add it, want to experiment with it, etc. Often its dependent upon your boss, what he/she wants and how fast. For example, I've been doing ASP.NET development for many years, but it's always the Web Forms stuff. I want to get into doing ASP.NET MVC. I've taken a couple of Pluralsight courses and now I'm ready to give it a shot. It would look good on my resume as well. I've discussed this with my current boss. She's not interested in my using MVC, because the other developer here doesn't know it. So, I'll do the project in MVC on the side, but I'll really be doing it in Web Forms because my boss has said that's what it's to be done in, due to the other developer not knowing MVC.

(Sorry, I know this whole ASP.NET stuff is outside the scope of SQL, but I think it still relates.)
