"All the sites, affected and unaffected, are designed using the same very, very simple template. All are equally well researched, written and illustrated with my own graphics."
So I am seeing something very similar. I have some EMD's that got hit and some that didn't. I dont see any correlations between the sites that got hit and those that didn't.
Not sure if this gets us closer to answers but I wonder if G was able to determine what is a EMD and what is not an EMD. Its certainly possible, but harder, for a algo. "bluewidgets" and "greenwidgets" one is a EMD and one is a company name. If someone is not in that business it could be hard to tell the difference. You would have to know that bluewidgets is a product and greenwidgets is just the company. Both terms could even get equal traffic. Splitting those apart is possible but not trivial.
I am leaning toward a general change in how domainnames are treated. Partly because I am seeing non EMD's hit in the same time frame and I don't think its chance.
