I don't know Tom, maybe he is in Medium but has not been promoted to me. The most prominent (Highest in the list), in a medium search is Tom Murphy writer of of Sand-Dams stories?

Why, when I do a search for Tom, do I only find folk talking about him, but never a link to one of his stories?

Why do you not supply a link?
