I miss running Slackware, if for no other reason that the weird look you get. For a decade I was running Slackware and a weird "package manager"(1). It was an incredible cool learning environment, but people though it was pretty strange.

I had a colleague once that was an absolute anthropomorphic distro. This man was Linux personified, and he literally walked around town with a Slackware live CD at all times. This man refused to use any other operating system, or any other programming language outside D or Erlang. He was pretty fun.
