Since this site is now in beta, it is time to have these conversations with the folks who are actually building this site. Please bring your comments and discussions to this site's 'meta' support forum so not to split these conversations. Thanks.
Elisp questions are always relevant to Emacs, e.g. It is hard to ask an elisp question that is not related to Emacs. I think they should be explicitly on-topic on emacs.SX, and new elisp questions on stackoverflow should be migrated over to emacs.SX.
