A lot of the ideas in this thread are almost identical to what the closed web monoliths have been doing for some time, and continue to do so today. As such I think they’re best mostly left to third parties (via apps available on various vendors), whilst the first party MB experience should tread carefully – I’m not saying it should lack features but I believe avoiding bloat ought to be one of the top priorities to maintain it as the core of the platform.
I truly believe the best version of the first-party Micro.blog experience is as the Naked Robotic Core. Either that or we’ll one day be met with Micro.blog Moments and Faves From Somebody You Follow filling up our timelines, rendering this entire enterprise a big waste of time.
