Well, we used to have such a feature. I think it's extremely helpful because some questions are extremely helpful to me; they're exactly the same questions I want to ask, and the answers in the same question are very comprehensive.
Also, I think it's a good idea to allow users to favorite their own questions, because the answers of some of their own questions are very important and useful for them, so they may have a need to check some of their own questions frequently.

They've been saying they're bringing the feature back. I don't know how much longer it'll take, though.0
