Personally? I don't have a problem with my topics, humble as they are, being shared on the blog...after all, once I post it, even in this community, there are tons of people out there with access to it who can then discuss it with their friends/spouses/relatives. I have actually submitted stories to the blog; those that have been posted had, not so much a "discussion" as "a bunch of points of view that I could use or dismiss but not really reply to the poster because not everyone comes back after the first day."
Perhaps though, if this is something that is going to happen, a default message needs put onto the "Post" page that says "Thread topics may be utilized as blog subjects" or "Once posted your story may be used by Ehell" or something along those lines. Likewise, if some blog post is to be discussed on this side of the website, a note could be attached to said blog post stating the URL of the discussion thread.
Also, I did not realize that blog posts were not to be posted/discussed over here; this is the first I can recall hearing about that. If I've contributed to a problem, I am sorry; again, I wasn't aware if it wasn't allowed.
