In the context of the EchoFeed shutdown, I noticed this post on Numeric Citizen about depending on single-person services, including Micro.blog:

What is the future of Micro.blog if something bad happens to its founder? What is the continuity plan? Micro.blog has done everything it can to enable data portability and ownership, but moving things around, even if you own most parts, is not as easy as it sounds.

This is worth answering publicly. A few years ago, I started forming an organization to more openly manage the aspects of Micro.blog that I control, but it stalled. I will get back to it.
