Having said that (and I appreciate the heads-up for a book giveaway, of course) the "rules" there MAY still violate Medium's. (Asking for claps, tagging of people - just be aware of that. At least you're not doing it just to yank people in because they are NATURALLY curious to know what you said about them - only to find out you said absolutely nothing about, to, or even relevant to them. Hope that makes sense!)
