In addition to normal conference discussion that happens on Twitter, I think that having a dedicated place for conference discussion (Slack, Discord, or something else) would be useful.
There are a few limitations with Twitter:
- conversations are not centralized around topics
- not everyone wants to use their Twitter to discuss conference stuff (some people are more selective about how they tweet)
- 280 character limit, no formatting
- hashtag gets flooded with well-meaning but possibly over-eager live-tweeters
Here are the benefits of using a messaging app in addition to Twitter:
- private discussion groups for sponsors, speakers, organizers to communicate about logistics or anything else that needn't be public
- no character length limitations
- easy way for attendees to report problems or as questions to organizers - including CoC violations
- public discussions can be organized around topics (either related to sessions like
Testing
andDevops
, or even more practical/off-topic ones likeThings to do in Austin
orPre-conference running club
or....Wurstcon
) - Sponsors can interact directly with attendees (with restrictions) - e.g., "Hey @JoeShmoe, you signed up for our drawing and won! Swing by our booth to pick up your free t-shirt!"
- official conference announcements are quick and easy (and delivery is ensured)
For announcements and stuff (including sponsor announcements) twitter or other social media is the best medium IMO.
I think adding channels to existing slacks/discords/gitters so for instance a PHP conf would maybe have a channel in the Laravel and Symfony gitters. This hits the topical communities within a single conference.
For more small self organizing I think a service like Telegram might fit better for conferences. I know that the Laravel community has used this for Laracon. The channeling to DM to group for something like telegram the last time I used it (which was a few years back) seemed to be better suited for events than a slack channel.
