I got my tux tattoo about 8 years ago, and had it touched up with the rest of these folks (actually, earlier on in the day because I had to MC the party.)
I think it's still as timely now as it was when I got it, and I think that if 30 years go by I'll always remember how important Linux was to me during this time in my life. If it weren't for my exposure to Linux, I probably wouldn't have become a sysadmin when I was a kid, I probably wouldn't have become a developer in my twenties, and I wouldn't be the community manager for SourceForge.net today. I hardly think that's a narrow focus.
ASCII a stupid question, you get an EBCDIC answer.
