Those are great, Steve. I think you should run with it.
Are you on me.dm? You could toss out the idea there with a hashtag like #newslogansforMedium, though I'm not sure that "instance" has much traction. I've had little response in a month or so on it.
Or toss it out on a Medium pub like Everything Shortform (150 words), which posts fast, so you might get ideas this weekend if you follow its very specific guidelines for submission. One of the editors, Kevin Alexander is the Usain Bolt of Medium. I saw that you're new to Medium, so I'll try to help: @kevinaalexander, if you see this, could you add Steve as a writer so he can try that if he'd like?
