<div dir="ltr"><div>Dear Agdakkers,</div><div><br></div><div>In his recent mail, Jacques raised an important point that got lost in the rest of the conversation:</div><div><br></div><div>>
- the community ought to pick a single communication system (Slack, Discord, Zulip, gitter, whatever, but just one!)</div><div><br></div><div>I wholeheartedly agree with this! Github does a reasonable job of keeping track of issues and feature requests, and this mailing list works well for broadcasting messages to the broader community, so these two we should definitely keep. But it would be nice to consolidate all other discussions and questions on a single platform.</div><div><br></div><div>Here are some of the current options with my opinion on them:</div><div><br></div><div>- IRC: An open system but based on archaic technology. I'm having a hard time browsing the history of a channel when I'm not always connected.</div><div>- Slack: Seems to be the de facto standard for many people and we used it successfully during the latest Agda meeting. However, it is commercial software and keeping a full history is not free.</div><div>- Gitter: Is well integrated with Github but feels otherwise quite barebones compared to Slack.</div><div>- Discord: Many features are more aimed at gamers than programmers. Some people used it for screensharing during the Agda meeting. It is commercial software and we'd have to pay for certain features</div><div>- Zulip: Has a nice threaded interface to conversations that can take a while to get used to. It is 100% open source software and is explicitly aimed at open source communities (<a href="https://zulipchat.com/for/open-source/">https://zulipchat.com/for/open-source/</a>). The HoTT community also seems to be using it quite effectively.</div><div>- MatterMost, RocketChat, Matrix.org, ...: These are other open source alternatives to Slack, but they seem to be less popular than Zulip in the type theory / formalized math circles.<br></div><div><br></div><div>My personal preference would be to centralize all communication (other than Github and the mailing list) on Zulip. But since this is an important decision, I would very much like to hear other opinions as well before we decide on anything.</div><div><br></div><div>Cheers,</div><div>Jesper<br></div></div>
