This should maybe be in chat or something, but has some crossover.
Just saw the latest Matt Cutts video and wanted to share it.
Now what he has to say on the subject of the thinking around ecommerce site content , quality, and uniqueness is probabaly worthy enough to be here anyway; but it isn't my reason for putting the link here.
It's how he reads out the question and the look on his face as he takes off his glasses; priceless.
Cracks me up.
Anyway, enjoy as well as learn (maybe)
