There are a few of these ad network sites around and this one has one of the more clearly defined explanations i’ve seen in a while. The heavy use of icons is what brought me to this site in the first place, I think they look really cool but aren’t completely necessary for the point of helping you understand the different networks available through influads.com but what they do is help you scan all the networks better. It gives you something interesting to look at as you go through the list – it made me read them all and get a good idea for what all is there. That’s a smart use of icons I think.
