I will forever fight this with saying that chat is an async medium. If you need a response right now, pick up the phone.

Worst offenders are people who say things like: Hey, how are you doing?

And then ... nothing.

Or maybe people are actually working on something. And your 2 minute question might cause them to lose 30 minutes.

This is why it is important to have multiple work-streams going when doing remote work, so that you don't sit around and wait until you have your answer.
