Google Users more Wealthy, Net Savvy
evil_breeds writes "A study by S.G. Cowen & Co. says that Google users tend to be richer and have more Internet experience than users of the other search engines, including Yahoo!, AOL, and Microsoft's search, according to an article on Infoworld."

Perhaps it was a bit bold to say regular expressions, its more permutations since it supports words and not letters.
But you can do things like "word * word"
You can also do something like this
"(I|He|She) (can|may|will) (search|find|locate)"
I agree with you that they would never (not atm) allow the public to have access to something that is turing-complete.
Yes, you can conclude that. The phrase "more likely" does not imply causation, merely correlation. If the data you gather shows that two factors are correlated then, without even trying to construct a causation model for this correlation, you can use one as a predictor of the other. The article is merely saying that the longer a randomly-selected user has been using the internet the likelier it is they use Google, and that the fraction of Google users with incomes over $60,000 is higher than the fraction of non-Google users with incomes over $60,000.
No, you don't. There is no statistical requirement that various groups you are trying to compare be of similar size in order to make comparisons. There is only a requirement that all your groups be sufficiently large to have a high likelihood of being representative of the population from which they are being drawn. WIth 1000 users and 9% MSN that's only 90 users, which is probably not enough to draw broad conclusions about MSN's user base, but the study as a whole seems to be mostly comparing the 52% Google users to the 48% non-Google users. That certainly seems like a reasonable number of samples to support the conclusion that Google use, technical experience, and income are all positively correlated.

This is probably what he means.
