You can use “Read my blog!” to end any ongoing face to face conversation. It expresses that you do not want to spend more time on your conversation partner because this person is getting on your nerves and is wasting your time.

This phrase suggest that your conversation partner should switch from personal talk to a mass medium. Before the internet came along, only celebrities could say things like “I have to go, why don’t you read up on me in Vanity Fair? Bye!” Today everybody can act with the same arrogance by quickly setting up a mass medium and refer annoying people to it.
