As far as Ruby and Python go: My first programming language was APL.

It's > How many people are programming in APL today?

The gentleman who wrote APL, Kenneth Iverson, recently died. (He went quietly, while at his computer, working at programming)

Over the last 20 years or so, he had shifted his focus to creating a new language, J, which doesn't require a special keyboard. www.Jsoftware.com has a downloadable compiler, loads of tutorials, free as in beer (not open source, different business model) and a very active mailing list.

Also www.aplusdev.org has an Open Source implementation of APL. Apparently APL has survived in the financial services niche.
