Perl.com has an article on Wikis written by Shlomi Fish. At the bottom, it says:
Shlomi Fish studies for his B.Sc. in electrical engineering and is heavily involved as a Linux and open source user, developer, and advocate.
How is one heavily involved as a linux and open source user and developer? It's like saying you're heavily involved as a driver and repairer of cars.. if you have your own car and change the oil once in a while.
