Best site (according to Alexa) is my article directory ~ 92K ish, the one in my sig, but my myspace site has 10x the traffic but is up at about 200K so dont really make sense.
holy... that's alot. What is the amount of visitors you are getting daily? if you can tell us, of curse. I was happy when sites I promoted got under the 400k mark, but 17k ... is extremely popular.
Alexa rank is not accurate there are many sites that have a good alexa rank because a majority of that sites visitors either have the alexa tool bar or another browser tool that pulls alexa rankings this artificially inflates the traffic. My site for example went from 9 million to 175 k in less than 6 weeks and has a weekly of 49 000 this is because a lot of people visiting my site are or want to be internet marketers. I have an alexa of 5000 or less in some countries and yet when checking my stats I only have a few hundred visitors from that country.
