My two cents
I personally actively refuse to use Slack because of their login system. Thinking back, its the main reason I chose not to use Prisma on a previous project (including one I’m using Dgraph with instead now). They would constantly push questions I had on Twitter to Slack. I don’t even use the YC Slack, I find the login system THAT inconvenient.
Discord > Slack for real time communication in every way (and free!).
Discourse / Notion / Github Issues / Anything (even email) > Slack for organising or storing anything you want to find in future.
If i was to get exactly what I personally wanted it would be the following:
- Discourse being officially supported.
- Discord community without official support which pipes all Discourse updates though a bot to channels representing the different categories.
