Another very good article with important tips!
I am starting to write articles here for "wider distribution" and will be sharing them in some of my usual hangouts-- I have a couple of niche blogs, several Facebook pages, I'm an admin on several Facebook and G+ groups. Been holding off a bit, pending the "weirdness" with HF-17/18 and the new rewards settling down... will be ready for a more widespread promotional campaign in May.
You have an amazing amount of knowledge in this field and you're a real asset to the community!
