I can see how it is not really a measure of anything tangible, and in the scope of things it is a pretty superficial "ranking" since we all know that we rank way higher than a snail site, LOL
. The site is it's own reward to me - what is really valuable is to donate to the site, as without funds to keep us up and running our rank would not matter a bit.
I did learn about this site originally from Aquarank, but not because it was #1 at the time, I was just cruisin'. I think it is good to keep us visible in the top sector, since that is the first thing you see.
