If you're building the application equivalent of JP Graziano or La Chaparrita Taqueria, make it human, scuffed up even. I'd like JP Graziano less if it looked like a Cheesecake Factory. Right there with you. But if you're building a tool, for developers, one that will mostly be used to conduct some kind of business? Boring competence wins hands down. Users and customers are scouting for competence. Most of the time, their antennae are not in fact up for individual artistic expression.
