Since the new page experience, I haven't seen an ability to make a top-level post as a Facebook user. It seems reserved for the page itself (FB users can instead comment/reply/message).

Yet, I still see examples sometimes - e.g. this one https://www.facebook.com/590520803229376/posts/743923074555814

For testing purposes, it would be useful to know how I can replicate making a post on a page as a Facebook user. This doesn't appear to be a tagged post either (no hyperlinking)
