On one hand, maybe I'm an asshole because I don't care to have three separate conversations about my weekend.
But there's something about Internet Messaging which makes it highly inefficient and basic small talk that should last 30 seconds in the office, last 30 minutes.
I tend to use phrases like "ttyl" or "cya" to try to escape the conversation. But it doesn't always work. So I end up just not responding after awhile. Either way I look like an asshole.
Slack or not, online communication lacks etiquette.
