I have noticed a lot of problems in the Answers list that seem not to be submitted by students. It's apparent because the problems are too general, or not worded like a student issue. I feel that I'm wasting my time answering questions that no one is interested in on a practical basis for his/her classes, and that my time is not well spent answering questions when no one will read the solutions. I think Wyzant should require students to specify the school and the class that they are taking, or at least submit a learning plan if they are in a self-study program, in order to submit questions on "Answers". This would go a long way toward eliminating extraneous questions. I am going to stop answering questions that I think are not submitted by real students.
