Darkseoteam.com has "stolen" content from Matt Cutts blog in a duplicate content test, and sure enough, a search for a unique phrase on his blog results in Google being unable to determine the original content. For example, a search for "carry the clickthrough from one NodeGroup to a different currency" that I grabbed from one of Matt's posts, resulted in one result - directly to the darkseoteam.com test. Perhaps now Google will see that it has problems with its duplicate content filter?
