Meh.
I've tried to understand how our membership can quadruple in the last year, our page views can septuple and our traffic can dectuple but our Alexa rating just goes up about double. I compare our traffic to the last site I worked for and see that their hills and valleys kinda match up.. when we have a spike, they have a spike, when we have a drop, they have a drop.
It's maybe a vague idea, but it's best to take a look a the 1 year look and not worry about the daily traffic.
It's also best to not worry about how much other people are making and look at your own bottom line... you have the members, you have the traffic, you have the revenue, then you just be happy and stop trying to positively comapre yourself to others...
