Flagging is for stuff that's inappropriate for this site
I don't think almost completely content-free promotional material is appropriate for this site, whoever writes it and whatever it is advertising.
I don't flag many submissions, and following the FAQ, I don't normally comment at all when I do. However, I don't know what actually happens when something gets flagged, so in this case I made an exception because I'm aware that Patrick himself is wary of submitting pieces like this. I didn't want anything to imply a personal attack, nor general criticism of links about A/B testing if they do offer new/interesting material.
