I'm Debian user from 8 years.
I'm a crytograph-freak. I've programed
SKS, a command line cryto-app, based on elliptic curves, as drop-in of GPG/PGP with simplicity as main concern.
When I started hear about bitcoin, it quickly drew my attention. Thus, here I am :-)
Those are awesome hobbies. I hope to learn about exactly those things. I'm glad more people like you are learning about bitcoins.
