It sucks that you have to be part of the elite AdSense Premium club (either by knowing someone in Google or having more visitors than the populations of certain countries) just to get the ability to customize your ads so they can convert better. Current AdSense formats all look like they were designed in the 90s and will have a negative psychological impact on your visitors.
In addition to customization, AdSense Premium also comes with private consultation. As of March 4 2013, however, Google opened up private consultation to anyone earning more than $25 a week [adsense.blogspot.com].
Do you think Google should open up customization the same way?
