I must get this notice a couple times a month. Can't tell if it's timed to match orders or not but it doesn't seem to match up, though I don't receive them in times when I haven't ordered anything so there is some connection.
I guess it is Amazon's weird way of trying to get people to review stuff.
But, the answer is no, I don't wonder if my reviews are getting noticed. I don't care. I don't think I've reviewed anything since 1990-something, so that should be a hint to their algorithms that I don't care. Seriously, what do I care if they get noticed? It's not like a get a commission if I write a review and someone buys that product because of my review. That'd require a disclaimer anyway.
Amazon also encourages me to leave a video review. Yeah, no.
