Is this enough traffic for a niche minisite?

I’ve been toying with the idea of setting up some niche minisites since reading this article: http://www.netbusinessblog.com/2007/01/09/building-a-niche-minisite this article… I don’t take this article to be the gospel, but it looks like a reasonable approach to take to get my feet wet with a niche minisite.
I’ve never done a "made for adsense" type of site, but I’ve been trying to soak up relevant info on the topic for the last few months.
