Do you see a need for a community platform for professional networking?

LinkedIn is currently the #1 public wall for professionals, but their groups are practically dead. Facebook Groups used to be the best place for professional groups, but it has gone down significantly since 2017. Discord, Telegram and Reddit are pseudonymous platforms, so building professional connections is hard. Slack is probably popular among the ProductHunt crowd, but I have never activated for longer term on any community beyond our own internal Slack, and I have tried many. If there was a focused community platform for professional groups, would you join one?
