In the early 1800`s, a man by the name of Noah Webster Americanized the spelling of many words. There are now a number of differences between how Canadians and Americans spell certain words.

It is important to keep these differences in mind when blogging. If you're blogging primarily for Canadians, then use the Canadian spelling. If blogging for Americans, use the U.S. spelling. If you're blogging for both, then keep in mind that the U.S. population is roughly 10 times that of Canada.

The following is a list of common spelling differences between Canadian and American words:
