Flagging is for stuff that's inappropriate for this site, like political articles, the latest injustice, politics, news stories, conspiracy theories and so on.
For stuff like this that you may not happen to like, just don't vote for it, and ignore it. I tend not to vote up patio11's stuff these days even though it's good, just because it gets so much attention.
But it is 100% on topic for this site and does not deserve to be flagged.
How much time has patio11 spent giving free advice and information here? So what if he also sells some stuff? That's what businesses do, sheez!

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.
