So I've started to work on a website that will (hopefully) have a very large userbase in the near future. This website is going to have a lot of user interaction (Mainly forum based).
I'm trying to decide what language and technologies I want to develope this site with. My choices are:
AJAX (Of course)
Ideally I want the website to run fast, with easy user interaction and a powerful language. I currently know PHP, and Im learning C#/ASP.NET but I can't decide which language would better for this kind of a website.
I've been told that for security, ASP.NET is better but for speed and efficiency PHP would be the better choice.
Can anyone give me insight? If I do develope in ASP.NET I would probably take an overall .NET approach to it.
