Because.
Sometimes I just want to reply to someone’s review ON their review, and I can’t, because many sites have that capability turned off. (I wonder why, heh.) So I made my own place for it.
It’s not all sassy; some of my responses might be just to show concordance, or maybe to point out where I disagree but I still appreciated what they wrote.
But it started because of the sass.
Note: if someone is just describing what they dislike about something or why it doesn’t work, that is valid and I don’t feel compelled to sass.
Some of the reviews/retorts will have referral links, some of them won’t. If it’s something I would personally recommend, and we can both get a few bucks off if you try it, then yeah of course why wouldn’t I include a referral link?
