Ask HN: How do you communicate in a remote startup?

Make conversations public by default. If you use Slack, make team channels, project channels, announcement channels etc. all public. Discourage 1:1 and private communication unless really necessary, especially for engineering topics. This single change will have an immense impact on overall company culture.

I found this can have negative consequences for more timid employees, junior hires or new joiners. People dont like sounding stupid in public, especially not in front of people they dont know. No matter how much of a safe culture you instil, human nature tends to prevail here and you get the loudest personalities being the the users of those public channels whilst others either dont ask those important questions or seek back channels anyway

Then these employees should use it as a growth opportunity. If you want to be effective at work you need to accept you'll be uncomfortable at times.
