Comment LinuxPPC -- Scientific Linux (Score 1) 867
Started of with LinuxPPC on my PowerComputing Mac clone.
After that, I believe was Yellow Dog Linux, although I toyed around a bit with MkLinux on pre-PPC Mac hardware.
Then SuSE at work on IBM PPC servers, and Mandrake at home. I loved Mandrake! Pretty sure Mandrake was my first x86 Linux.
At some point I moved to Fedora because of the good MythTV documentation for that distro. Also toyed around with Linux From Scratch.
At work, we used to use CentOS and now are on Scientific Linux.
