I don't want give away too much but you need A LOT LOT MORE LINKS. Also, the focus on humor is good...but don't half-step, go all the way and build a community around your blog. This builds retention but it also will take a lot of your time and energy and patience.
However, if you just want sales and a lot of traffic, create a text and thumb assembly line for your blogs and create TONS of them. Preferably leeching off existing traffic sources and interlinking
