"Size by itself isn't sufficiently descriptive. I think you've got to look at size in combination with trust and authority, and a number of other factors. There are many tradeoffs to take into account."
While I agree with this, I would say that trust and authority have been amped up, while google's semantic signals have been SIGNIFICANTLY reduced in the recipe.
I would venture to say that if an ebay or amazon user set up a page on ebay with the name "webmasterworld" they would start ranking very highly at a very quick rate for the phrase "web master world". I think it might be possible that they could even outrank the webmasterworld.com site.
Hmmm... think as an experiment I will try and set up an ebay account under mattcutts...
