When I started my career Linux and FreeBSD weren't as good as they are now. People we're not playing around with them nearly as much. So UNIX experience was hard to come by, and the big players like SCO, Sun, SGI, etc were really the only game in town. When Linux got good suddenly finding people with UNIX experience became A LOT easier. This also had the effect of decreasing the value of UNIX experience and all those people who had learned on big company UNIXes were now competing with kids who had learned UNIX systems from messing about with Linux.
