So I think the migration of my Doctor's Note newsletter #substack to #Buttondown is complete. Thanks to Justin from @buttondown for adding in redirects from the Substack URL slugs so that old links and searches go to the right place (and fixing up the image CSS). Here it is at its new home: https://newsletter.polaine.com
(Sidenote: the best thing I did was to use a custom domain on Substack just in case I ever had to do this. All the content now lives at the same URLs from before)
