I regularly check the "unanswered" section to see if there are questions I can answer. There are many questions in that section that I would like to be able to hide. For example, Edwin's question about Unmet Hours on Mobile has some discussion in the comments section, but no actual answers. There are also some old questions that were confusing or too general and were never answered.
There are a number of ways to sort there questions, but it would be great to allow each user to hide questions he/she doesn't want to see regularly.
