I have always noticed that some topics(like limits and algebra precalculus) get a large attention and multiple people want to answer it. I know these topics are fascinating and have always liked the different answers that users post. However there are other topics which receive little attention.
I do understand that this has to do with complexity of the question and the knowledge level of the currently active stack users, but what can we do as a community to get rid of this disparity?
One idea is to encourage people with higher knowledge to give time to other users to answer simple questions.
