Yes, I was out of town. I was in orlando for a number of days. If you read the instructions on the webmaster signup page, it says
"The toplist on the front page updates every 10 minutes and contains the top 50 referers. The top 35 referers also receive blind links mixed in the galleries. It makes a BIG DIFFERENCE if you can make it into the top 35. The #35 spot can get more than twice the traffic back as the #36 spot! You must make the top 50 to receive hits back.
"
Since the blinds are ordered in this way, as perm links and not by script, there will be a peculiar feature. Unless you are sending traffic when the list resets, you will not receive enough traffic back to make the trade worthwhile. I am sure you can work the mathematics of that out yourself.
For example, the whole time you are climbing to reach the top 50, you will receive no traffic back.
EXpect to send about 1000 per day to make the top 35 blinds list.
