There is "some" truth to calling Don a luminary in both the library and podcasting world, but what is even more certainly true is that having a "sense of humor" (and having the good sense to know when humor is appropriate and when it is not") ought to be considered an essential requirement in participating in an Epicurean community.
I can't imagine a group of "friends" who don't have a sense of humor among themselves.
Humor is easy to misunderstand, and it's especially a hazard since we don't "lock down" the forum to outside readers. But we have emojis and other ways to make things clear, and if something seems questionable we also have the Epicurean "frank criticism" (plus a private conversation system and private forum sections) to straighten things out - so anytime someone wonders how to take something, don't hesitate to ask.
