Ok, now that I have gotten the few devs reading this either going,
"YEAH, you are right, that is how it should be done."
"What are you talking about, the server code is essential for generating dynamic html that gets pushed to the client, that is why Razor (view engines in general) are used, so you can access your model right then, you are clueless."
As a former speech/debate member, I can go either way and see the advantages to both. Microsoft keeps coming out with new approaches to the MVC/Razor engine. They even have an IDE called WebMatrix which makes development of web sites EASIER (not completely easy, but easier) for non-developers. I love WebMatrix (so much I'm teaching a class on it in the spring (plug-plug-plug)).
So here is my attitude, I understand that if you are doing a marketing site, blog, simple web-presence site, server-side development is fine and really makes it easy to maintain from my standpoint and also, it generally (I said generally) works on almost any browser out there, since it is just pushing html.
But before you get all angry and emotional... stop and think about this:
So on the server, you simply need a way to pass down data (Json/Xml/etc...) and have server side validation of the request (a web service (pick your language, php/asp.net/ruby?)) and that is it.
Why is that so scary for people? Because Apple can't force websites to sell their application through the AppStore if it is available through the Safari browser? Because Microsoft can't sell another new technology (Razor/MVC4/5/6) so you have to buy the next Visual Studio? Because Google is all for it and they want to improve things (so far) and keep getting better without trying to sell me something at every new "release". I got a new OS on my android last night, did I have to go the apple store to buy it? did I need a new version of the iPhone to run it? did I need to download 23 security patches to make sure it would be safe after I installed it? did I have to order a new version of it and pray it works better than Vista and works on my hardware? The answer to all of those questions are NO. I simply pressed, "apply update". A few minutes later, my phone was faster responding, messaging had gotten selection of text better, and the notifications were faster and the toolbar was more readable. ALL FOR FREE. So yes, I am a fan of Google. Yes, I am writing this on a macbook, and Yes, I worked at Microsoft for several years and still work on Visual Studio everyday (and love it). But I'm learning nothing is black and white (even macbooks are grey now. hehehe). I like technology and what it provides for us. I don't need to be on one side or the other. I use what technology is appropriate for the task at hand. I still do some websites in iWeb, because it is easy. I use wordpress or blogger depending on how in-depth the person wants to go for blogging. I do use MySql or SqlExpress depending on what their host provides. It is all up to what the user wants and what best fits. Don't try to force everything down a single path. I love this quote,
