There is a question/thread over at slashdot titled What did you first do with Linux? Rather than copy my reply here, I’ll just put a link to my reply to that subject. I did have (and I mentioned it in the post) a get off my lawn moment when writing it. A fun walk down memory lane, and reading the rest of the comments on slashdot shows you how relatively early I was to the game.
It also makes me want to link to Anne’s idea of the best to learn Linux.
