This is a US History Resource Site that is used by highschools, colleges and universities nation wide. It receives over 5 mill hits per month and that number has been growing since openning in march of 2003 (we are nearing on our 1 year anniversary)
This site has been kept alive due to donations (I've received over $200 to date)
I don't really want to type out a long and detailed site description if its just going to get shot down because its an educational, non profit site.
But I'm wondering if this site has any selling potential, for either ads on a pay/month basis or the site as a whole.
Alexa rankings aren't really a good measure. You could go up at least that much by just installing the alexa toolbar on your computer and visiting the site once in a while. The only thing that matters is your visitors, don't base anything on alexa.
That being said, it's a nice site...I'm not about how much it could make but it seems like good resource.
