Man somedays I am just so happy to work for startups. I get to choose my own title. My last one was lead guitar, but it ended up confusing people so I changed it to just "lead". My current one is "software guy".
Edit: Oh sorry, I didn't know this was a serious topic, for serious discussion only. I'll just take my awesome title and go live it up, doing what the fuck I want. Have fun filling out your TPS reports.
