As a RN user, I'd be interested in actually seeing a piece of the content before laying down $100 for it. Maybe it's super simple stuff I already know. Maybe it's full of really useful techniques that I'll get tons of value out of. Maybe it's old and the breakneck pace of RN has left it behind. I wouldn't be able to know from reading this site.<p>Also interesting to see this disappear off the front page within an hour with 45 points. Seeing that many upvotes with only one comment here, from the author, makes me think it probably got flagged for shenanigans.
