I like serious job titles. I feel a bit funny handing the CIO of the Justice Dept a card that says 'Perl Grrl'.

My card says Senior Internet Technology Architect, but I'm thinking of changing to Senior Internet Technology Strategist for the next printing.

I also wouldn't want a job title that was tech-specific, like Perl Hacker, XML Guru, etc. I like more generic ones, like Software Engineer.
