The Elegant Email

I don't see a typo. The way I read it, Lopp doesn't believe that email cannot ever be used as a long-form communication method, but he sticks to a general rule of 3-4 paragraphs.

Not that rich. I could write a two-sentence email on why I think blog posts should be long and well thought-out without irony; why not the reverse?

There is a good point made. Which is that email sucks as a long form communication medium. One quickly gets lost (and as a result loses a lot of time) managing "conversations". It is also very hard to get some sort of continuity with email, because everybody uses it differently. People will often reply with multiple emails when asnwering a group of questions that you sent them. Adding their own questions on top of it, and making it a mess of spaghetti.
