Apparently I was somewhat mistaken in describing the new publication site. It is possible to cross-post, but they get first dibs. And first dibs, if yesterday is any indication, means a six to eight hour lag between posting, approval, and publishing. This puts it completely behind the news cycle, but I suppose it's up to them how they choose to run it.
Of course, there is always an option to publish exclusive content. I may try that once to see if one's content goes up sooner. My contribution today will go up later in the afternoon. Yesterday's post went live at 4 pm Eastern. Expect my posts later than usual from now on.
