Sometimes, on Amazon. I had some trouble setting up a new printer, so I posted a description of the problems and how they were resolved. It’s getting helpful votes, so maybe it was appreciated.
I wish more of the techie reviews were from dummies like me. The geek stuff is helpful to other geeks, but it’s all Greek to me, and not helpful when deciding whether to buy something.
I was recently invited to join Amazon’s Vine program (free books and stuff, invitation only) and I’m pretty sure it was because my (negative) review for Under the Dome got a lot of comments, and about 400 helpful votes. They probably wouldn’t have noticed me otherwise – I’ve only done about 40 reviews over a period of ten years.
I wouldn’t know where to go to review other stuff, like restaurants, clothes, food, etc.
