I built my first webbie when i was around 14 years ago, 2 years back... it was done on geocities using HTML coding, got tired of webbie designing since then, nv looked back.
Pre-high school, but 'twas merely helping my dad write source code. The first time that i've developed content and such for use on a website was this year.
Since it says "How old...?", I can answer that too. I think I was around 22 when I started using CAD, and it had just come out. That would make me around 30 when I built my first site for intra-company use.
I was in graphic arts when it was still done mainly by hand and cameras.
Does anyone remember drafting tables? Or, T-squares?
