Amateur. I make about 35k/month using only bash via CGI and some plain text files as database.
Serious? or joking? :) If the former, would love to know more.
Actually, I wonder if the creator of WWWBoard/FormMail/etc achieved that. It certainly would've been well earned. His stuff was everywhere (I used them a lot too).
Pft. I make 42k/month using only butterflies like a real programmer.
