I am thinking of making a website, which is a quite big one and may need scalability later on.
I know a little bit of asp.net , php and j2ee but not much, so before I start I want to know which language would be the best choice to make such a website which is meant to public exposure mostly not for something that works behind company's firewall.
I need to study any one of these to start making this website, so I want your opinion with which should I go?
