letters want to be read

I was reading this month's Harper's, the LeBlanc article on Doug Stanhope, and LeBlanc' points out that the place to perfect a stand-up act is in front of the audience.  What is the equivalent proving ground for a memoir?  If I had subscribers, I would publish like a Hardy serial and get feedback from readers.  Isn't that the way Wool developed into a book?

The book is epistolary ... letters want to be read.

If I'm having a conversation with someone don't I often go out of my way to be understood?

I'm starting in on March now ...
