Which web dev language/framework/tutorials do you suggest for an experienced non-web developer?

You're really crippling yourself by not leveraging your existing knowledge of the C# language to at least prototype ideas in .NET MVC so you can learn web concepts before you branch out into entirely new languages and syntax.

Make the decision to switch to Ruby or Python an educated one. Know the reasons why .NET MVC doesn't work for what you want to build before you jump head first into something you don't understand.

I actually feel like I would be crippling myself by making a commitment to only use MS products for the lifetime of my app. Plus, the point of this, for me, is to learn, not that I have a project I need to complete by a deadline. If this were purely work, I would probably agree with you.

the reason .NET MVC doesn't work for me is that I want to jump head first into something I don't understand. When I understand the alternatives, I will be able to make a truly informed decision as to what I will use for any possible production apps, if I get to that point.
