To expand a little on what Martin said: if there are questions that you think should be connected, then the correct way is to ensure that each is linked from the other by a hyperlink. It is a good idea to provide some context, but exactly what that should be depends on the nature of the connection. (I haven't looked at the questions you link, so this shouldn't be taken prescriptive in any fashion!) For example, if one question builds on another, then it can start with, "Following on from my question ...". But if a question is merely related, the link should be near the end, as in, "A similar question is ..." (perhaps with a sentence as to why).
The links should not be intrusive, so not cluttered with too much extra context. Just enough so that someone can make an assessment as to whether or not to click on the link.
