To be honest, I think there are strong alternatives now, but obviously none of them have the infrastructure necessary to sustain the entire Reddit community migrating overnight. Reddit's servers were flaky for years after the exodus, but we just lived with it because Digg sucked more. These days we have Kubernetes and commoditised hosting, so the infrastructure piece is largely solved. The question mark is around funding. Thankfully I'm seeing a lot more interest in funding for social platforms these days. VCs smell blood since Facebook signalled they're in decline. Twitter has decided any right leaning political views will be banned, so they're actively purging double digits from their user base. Alternative news and discussion channels like Substack are flourishing. This is the first real opportunity social has had for competition in at least a decade.
