I like this distinction between coders and developers.
The Coder is characterized by his proficiency in a narrow range of chosen skills.
By contrast the Developer’s single greatest skill is in being an applied learner.
I’m definitely not a coder. Alas, by this criterion, I’m also not a developer (because I do not pick things up fast):
Quite simply the Developer has a knack for grokking new [languages|frameworks|platforms] and becoming proficient very quickly.
I prefer Charlie’s framing. It’s not about speed, it’s about priorities:
I’m not a “developer” in that I’m obsessed with code and frameworks. I’m a “developer” as in I develop the users experience for the better.
