I had a friend back in the day that was a big Linux geek. He got me hooked when he showed me this crazy system that let me just type in a command and within a few minutes or an hour (internet wasn't super fast in my house in 2002), I could have something installed without having to search the internet for some potentially cooked installer.
That's the long way around to say I started with Gentoo, installed over the course of 3 long Saturdays with my friend over my shoulder and the install guide printed out on a stack of papers because neither of us had a laptop to look at.
I moved to Debian after a few months, but man portage was life changing.
