Does anybody have an explanatory link?

So, responses here are not terribly helpful.

The OP is specifically confused about the use of the prhase "such as" in the highlighted sentence. I said that this is not wrong, it's just formal and old-fashioned, but like most Americans I've had very little formal education in English grammar and with google I still can't find either the words to define it or a few well-placed citations by prestigious authors.

Go ahead, I guess. I am not positive that I am right about the last point, but I think it's a good hypothesis.
