Just to give my own two pence. I have been accepted into most affiliated networks i applied to (won't name them here). I only have blogger blogs and in my application i always specify that i am a PPC expert and have been for x years
When they get those girls to call thats where i seal the deal lol. Talk to her nicely and bullshit as much as you can. One actually asked me how much i make per month for my other networks and when i told her she signed me on and my AM called after 3 days telling me she was putting me on direct debit payment.
So i will say even if you dont have a regular website make sure your blogger blog or whatever has some good post and then bullshit your way in (it works but not all the time). Good Luck
