In the process of consolidating my personal blogging (going back to 2001) here on micro.blog. It’s going to take a bit of work to tidy it up - but I think it’ll be worth it.
@adders Good luck with this!
Similarly, I decided to migrate my back history of blogging from Squarespace to here, and it wasn't too cumbersome of a process (at least Squarespace had a Wordpress export in which Microblog would import, but I ran into duplication of photos that required clean-up).
Biggest hurdle I had was 301 redirects / remapped URLs from the previous site, but not a huge deal if you aren't overly concerned about page "equity" in the eyes of a search engine.
