I made my way here via Deborah Mayo’s sanctuary for frequentists like me, then to Booles Rings, to Carl Mummert’s home. Carl is a friendly face from mathoverflow.
This is a lovely, amusing post, yet there were no up votes! I tried to address that. Yes, I am Jewish. I smiled. Thank you.

Really? Empty?
I suppose that I don’t visit your blog then. 😛
nearly empty.
