Coming from someone who really likes the guy;

Casey's code game and logic game, quite strong.

His tact game and empathy game, not as strong.

Not trying to denigrate, just observing.

He was wrong in how he approached the team. Everyone lacks tact in this exchange.

Just because you don't think he was polite to some arbitrary standard does not make him wrong.

If people are this sensitive to "tone" and "tact" about technical matters, then we (as a community I guess) have much deeper issues then the technical matters themselves.

If you are looking for someone to do something for you, it's best to approach them in a way that won't make them upset with you. He didn't do that. His approach was obviously wrong as evidenced by the dust cloud it kicked up.

And your criticism of people who are "this sensitive to "tone" and "tact"" are equally applicable to Casey. He apparently didn't like the way the WT team talked to him. And it seems a lot of people in this very thread don't like the way the WT team is talking to everyone.

But you're not chastising Casey or everyone in this thread for being sensitive to tone and tact.
