When it comes to Medium vs Substack or Ghost...

• Can you customize the Medium interface to support custom widgets and themes?

• Have you tried cross-posting between Medium, Substack, or Ghost? Like, posting a long piece to Substack, with a shorter version on Medium and links for people to subscribe to the newsletter version there?

• How much traffic are you getting from the Medium recommendation algorithm, vs organic discovery, vs social media?

• For analytics, do they offer their own or is there a way to integrate 3rd party ones?

• How is Medium for complex content? Like text, graphs, videos embeds, gifs, Markdown, tables (HTML or Markdown), animations, and interactive scripts?

• Is there a posting API so you can automate or schedule postings?

• There's a mobile app. How much traffic do you get from there vs web or emails?

• Does the mobile app support mixed content widgets like above?
