Earlier quoted context omitted.
I think you're confusing communication throughput with latency. I also don't like using chat at work. It's not because I want less interaction , it's because I want less interruption . Email has a norm of asynchrony where I can respond to email when I reach a good point in my current task. With chat, the other party is presumed to be sitting staring at the screen waiting for my reply, so I have to drop what I'm doing…
I have never expected that the other party is sitting and staring at the screen in any Slack or chat I’ve used. An @mention will change the expectation of interrupting or not, but as someone who has used various chat programs for 24 years of my life, this ha never been an expectation I’ve had, nor one I’ve seen too frequently expressed. What do you think has caused that expectation in your mind? Do you wish that for…
OK, maybe not literally staring at the screen.
> What do you think has caused that expectation in your mind?
I think the structural analogue and communication style — even the name! — of chat is a verbal conversation. In a conversation, you say as little as needed and then pause for the other person to take their turn. Each utterance is pretty short so that you give the other party a chance to respond.
If you do that asynchronously, it takes forever to work through a sizeable quantity of content.
In email, the analogue is written letters. The expected asynchrony is high and in return the writing style accommodates that: each email is usually a roughly complete though with possibly some paragraphs. Since you know the person replying to you can reply to individual sections, it's OK to put out a complete thought. You don't have to shorten it to give them a chance to interject.
