I'll pile on to what Stephan has said: Just use IRC. If people aren't there, get them to show up.
I use Slack (via its IRC interface, naturally) and it works, but even using Slack's own client, I see no real advantage and I see several disadvantages. Cindy Cicalese[1] (who does things lik e Display Title née Semantic Title), just started as the new product manager for the MediaWiki Platform team at the WMF and, since it is WMF, started using IRC. She is using IRCCloud[2] which provides * Unlimited history access * Free apps for iOS and Android * 2 IRC connections * 100MB drag and drop file sharing * Full history export * Fast, personal support That seems pretty "modern", to me. But what do I know? I'm happy with using emacs's erc[3] and znc[4], so I'm a veritable dinosaur. Mark.
