Best thing. I found I am happiest below the UI level, better fit with my mind. So my weapons of choice are C# and F#.

I have gone through all the normal Basic, VisualBasic, C, C++, Java, JavaScript, SQL etc before I fell in love with C#.

C# is a C style language with some great syntax and language sugar and no pissing around with memory management :)

Over the last few years though I found Functional languages and those I really love. I prefer ML style over Lisp style though as Lisp is bracket hell. I picked F# as it interacts with C# and .NET so a natural fit. I dabbled with Haskell which is one of the most beautiful yet mind melting languages I have encountered. Just when I think I have groked it my mind melts again and I realise I haven't. lol
