Medium has gone the way of Twitter and Facebook.
I deleted my account last night. Unlike the blue two, however, I exported my data before deletion - not that I had anything to export with the others.
In the year between leaving Google+ and rebooting my blog it was my primary writing location so I went back over the posts from that time to see if any of it was worth keeping.
I identified 26 items that I may repurpose at some point although it will probably be a lot less once I've really thought about them.
