Seriously. It is amazing how many of these problems wouldn't be problems if people just behaved towards each other with even a minimal amount of courtesy. "Praise in public, criticize in private" isn't a hard rule to learn.

I wonder how much of this is due to tech's historic legacy as a safe space for the socially awkward. There's a fine line between a culture where the socially awkward are welcome and a culture where social awkwardness is considered a positive good.
