See, for example, the list of questions related to the List Category Posts Plugin: https://wordpress.stackexchange.com/questions/tagged/plugin-list-category-post
(It even has its own - detailed - tag wiki.)
Is this appropriate for WPSE, or should these questions be directed to the List Category Posts Plugin support forum at wordpress.org?
I think this plugin is a good starting point for this discussion. I note that it has a particularly low - even by normal WPSE standards - participation/activity rate and accepted-answer rate. It doesn't seem to be adding much to the overall WPSE knowledge base.
