Hi everyone,
I am currently in graduate school for Computer Science and really loving every second of it. There is so much to learn and I want to learn it all!

But seriously, I would like to start focusing on maybe one or two languages in depth. I would like to become an expert in these fields and use my knowledge to do freelance web development work. This is my ultimate dream.

I am interested in server-side work, so any of the languages would be great to really dive into.

My question is this: what you you recommend, in light of what's in demand, what's lacking skilled professions, what's conducive for freelance work... what would recommend I focus on for my niche?

Thank you very much for your help.
