thanks for the support and feedback.
one book i recall is The Elements of Style, often called Strunk & White: https://en.wikipedia.org/wiki/The_Elements_of_Style
otherwise i've not studied writing per se, just "practice" a lot in blog posts like this one.
my shtick is to add humor, remove qualifiers, stay conversational. all tips real writers would share too, but maybe not the same writers. ;)
