I don't visit ask.sagemath.org much, so others who are regulars there may correct me, but it seems that the whole downvoting/upvoting / karma / accepting answers mechanism of this forum may have little value, as most questions have 0 or 1 answers. So if that's lost in the migration, perhaps not much is lost.
ask.sagemath.org receives questions and answers on a regular basis and still today. Not later than last week, a user was happy for my answer : https://ask.sagemath.org/question/77821/stanley-reisner-ideal-from-polytope/. Also, I would say it is mainly a community of *users* of SageMath. Questions are asked by users. But, also, the answers are given mostly by users that are no so much developers. For instance Samuel Lelièvre, Karl Crisman, Thierry Monteil, rburing are among those [https://ask.sagemath.org/users/] who have answered the most questions and gathered more that 10000 points of Karma. I don't agree that this has little value: I dare anyone here to reach this value! But you will not see these top Karma users in the top committers of the git of sagemath. It is just another way of investing the community. By answering questions on a daily basis, Samuel, Karl and Thierry gathered through the years an enormous experience of what a normal user of SageMath needs are, and what improvements should be made to SageMath, etc. I have great respect for them and for the time they and many others have spent on ask trying to provide the best answers. I think moving ask to some website made for developers (e.g. Github Discussion?) is very bad idea, because it will kill this community of users which is still alive today.
