Looking to learn something.

I would like to expand my skills, I only know HTML and sumz Visual Basic.  I would like to learn something new.

What should I look at now?

I did !!!

I wrote some fast utilities for converting file formats. All the C#/Java people were liek "WTF do u think ur doing... gcc... on a workstation... IN MY CORPORATE ENVIRONMENT ?!!!" But they all thanked me later, as my utilities were fast and small.
