Well i know for sure that whenever you post an answer on musing.io there is an option that allows you to tick “post to blog” what that options mean is that will enable you to post your answer directly to steemit as a post of its own

You need to enable that option if you really want your answers to appear on your steemit blog,what will happen if you don’t enable that option you may want to ask??well the answer will still be visible on steemit but it will appear under your “comments” but it won’t appear on the “blog”
