Apparently that catches a lot of people. I think chopping up an article into an array of sentences, and throwing a few into google would be a good approach. Submit 25% of the sentences to google as exact phrase matches. Throw the first 10 result urls into an array for each. Sort the urls and see how many are the same. Justin
