I can understand the tons of ads to offset costs of hosting, but when popups come along, that means something bad. I'm pretty sure it was said that this site would be popup free when the ads were placed and when premium members were introduced. But going against your word is a negative thing to do.
I'm sure it's nessicary, but don't say you will do something, and then not do it. It's against common sence.
But other than that, pspupdates has made me quite happy, whenever I come, I usually click one or two ads to help create some revenue.
EDIT, I take that back, it seems that it has be just some insolated incedents. I'm sure they are just comming from the other ads. :) makes me a happy man.
