Thanks Justin. That’s a great idea and we had the same thought.
For now, we know publication owners are feeling the “3 tag” limit as being very constraining because they are using tags for things tags weren’t originally meant to do. For this reason, we are expanding the number of available tags from three to five.
Will this make Medium less tidy? Yes, a little. We are working on other ways to avoid the dilution of the tags, and other features for publications so you won’t have to be as reliant on tags.
Thank you for the feedback!
