Am I the only person who thinks nouns should stay nouns?

Surely not. However, I came across this little gem today:

The Associated Press has just informed our editorial department that "unfriend" is officially a word.

So, not only is "unfriend" officially a word, it's OK to use it as a verb? I don't accept "friend" as a verb. I don't really like "text" used as a verb.

But then again, I'm a word nerd and a grammar Nazi. So maybe my opinion is that of an old curmudgeon.
