I'm drawn by

"Edit-This.Page - Instant Publishing, Zero Friction"

"Easily share content with *zero* need for apps, logins, subscriptions, blog setups, or domain names."

"Seamlessly collaborate using only your web browser - without any sign-up"

but then when I attempt to share, I get

"You must be signed in".

Not Instant Publishing. Not Zero Friction. Not without sign-up.

Sorry to have to say it, but this looks like a scam.

Shame, since it otherwise looks like it could be great.
