When I reading a topic (a question and its answers) on the main board, a list of other questions shows in the right-hand column: titled, "Related".
When I navigate to one of these questions, drawn by what seems like an interesting title, https://skeptics.stackexchange.com/questions/3816 I find it's closed: with no answers; and no ability to add an answer (since it's closed).
So: not a satisfactory question to advertise as "Related".
More of a problem in a site which has many closed questions.
