Comparison Engines: Quality Score Impacts

PPC Super Affiliate has a great post on changes to Google's Quality Score ranks. The key phrase from Google:
The following types of websites are likely to merit low landing page quality scores and may be difficult to advertise affordably. In addition, it’s important for advertisers of these types of websites to adhere to our landing page quality guidelines regarding unique content.

* eBook sites that show frequent ads or install malware
* ‘Get rich quick’ sites
* Comparison shopping sites

This is a very interesting development, going into Q4 when the comparison engines typically raise their rates...Will they be able to get the traffic they need? I'll be curious to hear what Brian Smith or Scott Wingo have to say.
Amit has a take from the affiliates perspective.
