> It should be considered common courtesy that when you ask a question you have at least attempted a bit of research to find the answer on your own.

In my professional experience. About 1 in 10 people does that. Maybe, 2 in 10.

In my line of work, its certain peoples' jobs to know certain things. If I need a piece of information that somebody else is responsible for understanding, I'm just going to ask directly for what I need instead of trying to research it myself. To research it myself would mean attempting to do somebody else's job, which is just unhelpful for everyone.

There is a line between "somebodies job to know" and you just being too lazy to look at the documentation/do basic research.

That experience is better characterized as unprofessional, then. ;)
