This is an email from Ravings of a Quarantined Mathematician, a newsletter by MathAdam.

What would you like to see from MathAdam?
Your feedback is important. Really. It is.
After the publication of What If Your Cat Became A Black Hole?, a lot* of people signed up for the MathAdam newsletter. It got me wondering:
What have all these folks gotten themselves into? (Yes. Gotten is a word. I checked.)
The simplest thing to do is to ask.
So, I’m asking.
What would you like to see from MathAdam? I have an itty bitty form for you to submit your responses. All respondants will receive warm feelings.**
Thanks much! And I look forward to sending more mathy/fizzixy stuff your way.
Adam
