@tedmielczarek Sending attractive email messages to large groups of addresses is still difficult. Which is why @buttondown et al exists. The value, unlike a typical blog, is that the publisher has direct access to the reader and - presumably - a direct line to their inbox which may _never_ change.
I love newsletters in that I like regularly published content on a schedule that feels as though it is written for a specific readership. But I prefer RSS as the delivery mechanism personally.
