Maybe, but personally I'd be pretty weirded out if someone who could figure out the significance and use of the string I posted could not figure out curl.
Based on personal experience, I'd respectfully say it's just you. I do see your point, though.
I've met plenty of people who could code up a simple web UI but weren't very familiar with the underlying HTTP protocol. I guess my point is that knowledge of the protocol and web infrastructure is more valuable (sometimes) than just being a person who knows how to slap something together.
Is that just me?
