I couln't agree more. Some of the topics are just not conducive to clicks. Good site site with nice information, though.
yeah.......... if the niche is just not that good maybe slowly shifting your niche a little bit by adding content on a differen "human" topic may help Also maybe try a verticle link unit in your left border.
you should be getting a lot more then a dollar a day eben with only 70 uniques. Try to create more content rich pages with higher paying keywords that still relate to the topic of your site.. get this page into search engines
One of the problems I see is that even though you have a "lot" of content, it seems to be about a lot of different topics which makes it harder for AdSense to figure what your site is about. More importantly it makes it harder for search engines and most importantly readers to figure out what your site is about. I've seen posts from the worlds smallest cat, to keyboards, to morality. It will take quite a bit of time for Google to figure out what your blog is about. I put the word "lot" in quotes when refering to how much content you have because in the grand scheme of things, you really don't have all that much becasue it is so unrealted to the overall theme of your blog. Try creating categories to better group things together and following mistermix's suggestions on improving your SEO.
