Apparently Microsoft Word now accepts the words:"blog," "blogger," and "blogosphere"  in their spell check. Doesn’t that make all you bloggers feel validated? This from AM/NY.

Microsoft Word loves to underline misspelled words with angry red
squiggly marks. But as of the 2007 edition, currently in beta testing,
words like "blog," "blogger," and "blogosphere," won’t be singled out
for the spell check treatment. Apparently "blog," at least as far as
the programmers at Microsoft are concerned, is now part of the English
language.
