Who are you trying to make it "right" or "optimally" for? The developer community or the end user? Unless your end user is the developer community, I doubt they give a crud if you are using jQuery or all of this stuff. As long as your app is doing what they want it to do and doing it well, that is what matters most. If you want to make a simple website, all of this is way over-kill. That is one of the downsides with these discussions. People are lead to believe that all of this is needed to "make a simple website". I am not at all opposed to learning new stuff especially if it is going to make your job easier, but don't feel you have to abandon your current toolbox and buy into a new one every few months just to keep up. That imo is madness and will only hold you back from getting stuff done.
