I’ve gotten rid of the Book of the Week section on the right sidebar. I’ve only gotten a few clicks, and haven’t gotten any purchases through it, so it doesn’t make sense to continue. If I can build up a stronger following in the future, I may try to bring it back again, but the extra work of changing it every week isn’t worth it at this point.
I have a feeling that the lack of a mobile site that uses the sidebar is the biggest reason that it hasn’t turned out so well. I plan to fix this in the future, but at this point, I really like the non-mobile look and I don’t want to change it, but I’ll probably have to.
