I should add you can see the tumblr effect by putting almost any word in front of the version with an e (mug). It will return some version of a tumblr blog. I could list about 50 other examples of domain names that are close approximations to everyday words suddenly ranking very highly for perceived missed spellings by google. Apply that out to all of our verticals and we have all been shuffled down. Apply it to the tens of thousands of near spellings and we can easily see how spot 2 is now spot 4 or 5 on longtail that is impossible to track.
This example is particularly relevant because the same search in bing returns actual products without the tumblr blogs.
Ted would better understand why this is happening, trust ranks maybe? All I know is it also comes into play with the duplicate sites as I notice it is triggered most often when the domain name being used by the merchants running keyword clone sites relates to the keyword search.
