Mastodon reminded me how fun microblogging can be. I think the future of blogging is still found in the details, in the not-so-bloggy platform divergence patterns we've seen in the last two decades. Blogging platform as identity maybe.
It's like asking what the future of writing is, in a way. On the one hand--the future has never looked brighter. On the other hand--wtf are we even talking about in particular, and why are you shopping for typewriters?!
To identify a better blogging platform I'd start with subjective identity characteristics. What do you like (who cares that everybody thinks the world likes what they do) and what platforms really fit that style well? That's the money for that platform. We are still zooming in on parts of the greater fractal and what they can mean for little sections of the population.
