Sure, I do it quite often. Chrome will format the code if it is minified so that is easy, and you can quickly jump around and see what is happening. If you know your front end frameworks you can pretty quickly tell what they are using and how it is all put together even when code has been obfuscated. I definitely use view source when debugging my own code or testing layout changes I am playing with since it is easy to still adjust the css and view the changes etc. The javascript console is valuable too. I guess for me it is usually less about finding out how things work now so much as debugging an issue or finding a vulnerability. I have found a number of vulnerabilities using view source on products out of China that have built in web servers, like ip cams and the such. *edit -- When I think of view source I think of the complete dev tools, not just the single "view source" tab.
