Suggestion, Molly: go back to your earlier pieces and add links to the later ones. So that someone could pass along a link to your first story, follow immediately to the next, and so on. (Disclaimer: I'm lazy, and I want to be able to pass along a single link to friends.) I've done this with my Nerd Romance series, and I've occasionally seen sudden streaks of readership as someone clicks from one story to the next.
