It looks like Slack became a main communication tool, at least for some teams. I'm a volunteer contributor (who previously worked in Readers Web Team) and I'd like to have a way to contact the Readers Web Team to talk about ongoing projects.
I'm actively working on Feature Management and I'd like to have an easy way to talk with people instead of exchanging emails/text messages. Having an access to some channels on Slack (like readers-web) would be super useful for both parties.
