I would like to as a general question on this forum, and I would appreciate any knowledgeable answers.
We are going to start a new company that is going to create a website that will have both static and dynamic content, and it will allow users to search for and communicate with each other via Skype (or something similar) and form groups.
I have asked everyone I can think of to recommend which platform, languages, etc. we should use. I am just finishing a degree in Network Security, and my programming skills are very basic (I'm not competent to make an informed decision). I am receiving different answers. I want to build this site in the best manner possible in order to be able to scale to perhaps 20 million users (maybe a million or two simultaneous users at certain times).
So, if you were to build a site with the aforementioned content, what would be the best way to build it?
