Thanks, I am more interested in developing social websites with modern look and more performance, I mean like the design of medium.com or hashnode.com, I think they do render the first page fully canonical HTML, and then every subsequent request is rendered using the js framework GETing some JSON which gives more space to the server to do other work.

I am really interested in this approach but I fear about the SEO and any additional unnecessary complexities like compatibility with old browsers and OSs especially in Android.

Take a look at russian vk.ru

It's lighting fast compared FB and does all the same things. Really neet. FB makes my laptop literally over heat.

If you fear about the SEO, start with Turbolinks.
