I think the concept of the Series feature is cool, but its execution leaves much to be desired.
I’d already started publishing a series when I found the new Series tool — but Medium wouldn’t let me migrate my existing stories into a new series. I would have had to cut and paste, which just felt like too much trouble.
And only being able to read Series on a phone? That’s too limiting, and in my opinion, ill-conceived — and sealed the deal on keeping the series I’d just started in the old format. Why limit me on who reads my stories to just those who read on phones? Call me old-school, but I average about half my time on Medium using a laptop, and half on a phone. Isn’t providing more ways to access a story better?
So, my take on the new feature is…meh.
