Is there any other good way to get better Quality Assurance on the items on the Application Center?
It seems that community ratings just aren't adequate. I don't mind that lots of items are a bit thin in the content aspect. But bad advice is a problem.
Take this example, where Matrix-Matrix multiplication is suggested primarily in the following way. Note that, apart from using the wrong package, it produces a matrix instead of a Matrix.
I saw another App Center item in which, for no adequate reason other than wanting to use it as a top-level name (when any other would do as well), D was unprotected. There's a real QA need there.
