@mjmoore52 @albertocairo @DataVizSociety One obvious problem with Slack is that an account with ~4000 users costs > $20,000. You need a lot more Patreon supporters for that. But I'm sure they can solve this some way or the other (i.e. Slack offers a 85% discount for certain non-profits https://t.co/wFBriS7Vhv)
