The fediverse is exploring most variations right now
Where are:
- private spaces
- messaging
- chat rooms
- my-space style personalised pages
- Fusions of any of the variations you're thinking of?
- Microblogging + Reddit
- Blogging + reddit
- Youtube + others
- Any and all
- Social RSS feeds like Google Reader
- Wikis
- Market places
- Subscription based content platforms for any format (eg blogs like substack or videos like nebula)
- Heavily privacy and safety focused platforms (with, eg, abilities to control who can ever respond or see your content)
- Video shorts (which I personally hate, but there's probably something of value there)
- Computationally rich posts/pages ... that is, content that is not merely static text of an embedded video but contains interactive components with highly customisable graphics.
Without wanting to be aggressive or critical of you here ... there's a good chance you, like many of us, are stuck thinking the internet can only be so many things because that's all we've been given for a while (like a long time ... like Twitter and Youtube have been around for longer than half the age of the internet, like we've arguable had real stagnation that might look like the age of Dinosaurs from the future looking back).
