Mark, remove my blog at there 🙂 serious. I’ll add my blog again if my content good enough to tell people how to make money online.
Make sure 45n5 choose a right blog to get list at there.
Look at Technorati Top 100 blogs. They select quality blogs only to get list in 100. I think 45n5 should to add another formulas to the rank. Google PR + Alexa + Technorati + RSS + Vote + Bla Bla Bla.. Just my 2 cents.
