I know the domain is weak, but that can be fixed easily. This is a site with over 200 pages, and has potential to have an unlimited amount. It's also good, because for each page, there is a niche, and the ads on each page are different, which is good for returning visitors. It is very easy to add around 20-30 pages per day depending on how much you are willing to work, which is also an advantage. Link exchanging with other sites is also easy due to the wide area of topics.
