I'm talking about the two modes where you invite readers to rate the product or recipe. How can that be done until they have read most of the hub? So it goes near the end. How will anyone else see it until they've read all the way until the end?
I think it's best to place it near the top so that as soon as the visitor lands on the page she knows she has the option to rate the article. No matter where you place it though, you can't prevent people from rating without reading the article. There will always be readers who just skim and rate. I wouldn't worry about too much.
