This is a valuable point. I no longer just ask questions of people: I try to be respectful of their time by trying hard myself to figure out the answer first.

The upside is that I learn a bunch of things. The downside is that I rarely have a question for anyone anymore. I'm either too lazy to dig into the question online to be sure that the question is worth asking, or I figure out the answer on my own.

Talking to someone who is a master at something is much more valuable than the internet... but the definition of a "stupid question" is becoming smarter.
