I know that I have been very surprised by the stuff I see when I go sign up for mainstream sponsors.
Lots of them insist of using their banners from their site, no changing creative etc. Which is cool, I have no problem with using their bandwidth, but seems about 90% of the time their fucking banner doesn't come in. Something they need to learn quick is that if you are going to host your advertising, you better keep the fucking server up.
Then a whole lot of them only want to deal with established sites with proven traffic. Now I can totally understand this from their perspective but if you are just setting up your first couple of mainstream sites, you might not have proven traffic yet. If you expect that I am going to go change my whole site around 6 months in just to accomodate you as a sponsor, you got another think coming
