I think the Internet needs an open trading platform for ad space. Something like an overarching OpenX. Google has their proprietary bidding system for Adwords, however we need a similar system for blogs, local websites, etc. Competition breeds quality and dynamism. Another thing is that advertisers are tied to the same medium for long periods of time. It would be great to have a platform that could switch an ad (banner ad in this case) from one portal to another, depending on price, date and web traffic conditions.
