Well, this has been enlightening. As reported, a feature on DailyCheapReads.com boosted sales of "The Job" at the Kindle store, although not to the great effect that I first thought. The next day, sales went back to zero, and it's been that way ever since. So getting on a prominent website can substantially help a book, but once it's no longer at the top of the front page the effect is over. The only thing I can think of to do with this is, since these sites are mostly blogs, is every time a new feature or review is posted, leave a comment about the new post. Probably won't garner much attention, but what else is there?
In other news, the second installment of the Poncey stories is finished in first draft, and the opening story is undergoing its editing process. Don't know what I'm talking about? Stay tuned for more details!
