Coldfusion
When I started at Mannix Marketing they introduced me to Coldfusion. At first I thought it was just another programming language but after learning a little bit about it found it probably more powerful than most web programming languages out there. Its biggest downfall and the reason why its not as popular as other programming languages is probably because its not free. I'm not sure the exact price, you can check with Adobe, but it cost quite a bit of money to have it installed on your server. If you can afford it, I definetly suggest you take it out.
