https://aiaustin.wordpress.com contains a backup of Austin Tate’s Blog for posts up to 30th September 2018 created via a WordPress Blog “All Content” export and via a top up for October 2018 to May 2019 “Posts” export from http://blog.inf.ed.ac.uk/atate/.
The original WordPress theme used is Twenty Ten which has a main content width of 640 pixels. Twenty Ten may not be supported on wordpress.com in future. Twenty Sixteen is a similar theme but has a narrower main blog post text area. So a lot of the images may not lay out side-by-side where they were intended to.
