Slack has raised our charges by $195k per year

We had the same issue many years ago with the reactiflux community. We ended up moving to discord and that was the best decision ever. Discord has been an extremely welcoming place for all these kind of communities.

Let's revisit this assessment in a few years.

we've been using discord for years, it's great. Its model for making money is different, its primary market is gamers. Servers are content for their users to consume and they charge the users directly.

I'm a Discord user myself, in private as well in job context. But we all have been here long enough to know that the only reliable constant is change.
