I think what distribution means is that they will circulate those pieces to your readers. If you don't have anyone who is actively reading you, the piece won't get read. I don't think it means it is publishing it in any sort of magazine. Another idea is that by distribution it means when they send the weekly or monthly email to people, your article is it if it has been distributed. Again, however, it is only being distributed to your followers. If your followers aren't really following you, then obviously you are not going to get any reads.
