But the network effect of a social network is a status quo we kind of just let happen, and maybe that needs to be rethought. You could equally imagine a case where email was a walled garden — where Gmail users could only send messages to other Gmail users, Hotmail to Hotmail etc — and someone said "well, that's the nature of email platforms". It doesn't have to be this way — if we had a common protocol for 'social' (or used & improved the ones that we already have), you could have interop of posts/comments/media between platforms and then the platform's 'secret sauce' be curation of messages, discoverability of people you might want to connect with, etc. Facebook could focus on connecting with friends & being free but ad supported. Instagram could be only media posts & supported by sponsored influences in your timeline. Twitter could be focused on current events rather than your friends and be subscription based, etc. Similarly with IM, we had lots of competing IRC clients when that was a thing. As products, you could easily create competing messengers that could speak to each other. You could even have additionally things on top e.g. if you have a FB<->FB message it can support 'stickers' or whatever that are outside the spec, but similar to browser development they _do_ get added to a shared spec that isn't controlled by one company.
