I feel like I'm starting to understand this whole Fediverse thing. And I quite like it. There are some gnarly issues that I can see, and I do also have concerns about how it scales (maybe this isn't a problem, don't know), but I think that we don't need a centralized microblog service like Twitter.
The core Twitter value proposition is very stable. Stable enough to be a protocol, instead of a product. The innovation can happen at the product layer on top.
