I would like to chime in on this topic, but first, hello to all the great webmasters here (I haven't been around in a while).
First, I heard about this algo change a few weeks ago and thought, hey, two of the ad networks I use REQUIRE their ads to be "above the fold."
Second, my home page and a lot of other pages are so full of self-sold, paid ads and ads from networks, I'm almost embarrassed to mention it, but, I remain #1 in the SERPs for my main keywords, so, I'm not worried about this at all.
Third, I agree with most of MikeNoLastName's post about 10 slots above mine.
Fourth, Google continues to try to impose its will on publishers and I believe most could care less. Google has long had far too much power and control and I believe that their "500 improvements" are a lot of blather, which will result in their ultimate destruction.
Fifth, I switched my default search engine to Bing six months ago because it was BETTER. So, should we follow the usual path, like using PCs rather than MACs because "everybody does it?" Or, will the combined intellect of the internet find ways around the behemoth that is Google and search using Bing or other solid engines?
Google has been the champ for a long time, but, as we are all well aware, the crown changes hands over time and I think Google is already dying. Just look at their desperate attempts to integrate Google + into everyone's lives.
They're done for and the web will be a better place when they're knocked down a few notches.
(Was that too negative?)
