Well, Lori mentioned in her blog that she gave some grammar explanations to Pamie in her blog. If you don't want to follow all the links, I'll just tell you that the question was about the placement of "stuff" when you have quotation marks.

It seems like, in American English, it is a rule to put the commas and the periods inside the quotation marks, although logic would put them outside. This convention always intrigued me, especially when I was working on text parsing on the web. This discussion got me so intrigued that I decided to search about the reasons for it. Actually I found a couple of websites with explanations that made sense:

From Tina Blue: "Well, it seems to be the result of historical accident. When type was handset, a period or comma outside of quotation marks at the end of a sentence tended to get knocked out of position, so the printers tucked the little devils inside the quotation marks to keep them safe and out of trouble. But apparently only American printers were more attached to convenience than logic, since British printers continued to risk the misalignment of their periods and commas."

From Charles Darling: "There are peculiar typographical reasons why the period and comma go inside the quotation mark in the United States. The following explanation comes from the "Frequently Asked Questions" file of alt.english.usage: "In the days when printing used raised bits of metal, "." and "," were the most delicate, and were in danger of damage (the face of the piece of type might break off from the body, or be bent or dented from above) if they had a '"' on one side and a blank space on the other. Hence the convention arose of always using '."' and ',"' rather than '".' and '",', regardless of logic." This seems to be an argument to return to something more logical, but there is little impetus to do so within the United States."

The conclusion is that, similar to the use of the "Imperial" System of Measurements, it has a historical background. But unlike it, nobody is even thinking of changing back to the "logic" way of doing it, although we don't have the technical issues of printing with commas and periods that are not between two characters.

Oh, well, who will ever understand these Americans? ;-)
