Brad Feld wrote a post today about cross-posting to Medium.

He says: "...when I publish something on WordPress, update it, and then publish it again, it doesn’t update on Medium."

I've been theorizing why Medium doesn't flow-through updates from external CMSes. 

I think it may have to do with the highlighting feature. 

Here's the narrative...

Suppose one of my posts appears on Medium.

• Then someone highlights a section and comments on it.
• Then I update the post.
• What happens to the highlights?
• The offset could have changed. 
• The text might have been deleted. 
• Or the text might have changed, rendering the annotation obsolete.

The highlighting feature in Medium is a good thing.

I expect this is something they're working on.
