You should learn a new programming language!
Learning a new programming language is great for two reasons:
- It expands your mind. Your brain gets exercise when it’s forced to think in new ways.
- If you’re building something big, take the time to learn the best tool for the problem at hand.
I learned this the hard way when building Zyked.com. At the time, ASP (the old one, not .NET) was all I knew. I spent almost a year slowly building a large site, before hitting a wall when I came to AJAX stuff and Facebook integration. I then learned Ruby on Rails and rebuilt the site in 1/10th of the original time.
Learning to be productive in a new language, framework, or tool rarely takes more than two weeks. It’s worth it.
Functional languages are hyped right now because they scale better across multiple processors.
Clojure (like LISP):
