The reason I am writing about this, is because I reported this issue probably over two months ago. Basically, if you try clicking on a Google AdSense RSS Feed Ad within Safari, it does not take you to the destination page. I don't click on my own ads, but I happened to click on one of my ads when I was actually interested in the advertisement offering. When I did that, I got the same screen I got today, which looks like...
I first thought it was an issue with the way I configured the ads in my feeds. But then I signed up with FeedBurner and they put the ads in for me temporarily here and I clicked on it and guess what, same error. Now I assume that it has to do with my browser being Safari. It did not work in Bloglines when I tried about two months ago, I also don't think it worked on Firefox for Mac but I am not sure. I never heard back from Google on this, the email probably got lost. I wonder if this entry will help get more answers, if not from Google, at least from readers. Oh, do not click on the ads, it is against the TOS for me to ask you to do that, so do not click, please (I am serious).
I started a thread on this topic at DigitalPoint Forums (where I like to post AdSense related topics).
