So why does Facebook want to trademark this word? And what would be the ramifications of this trademark? Would you have to pay a royalty every time you used the word?
My last name is a trademark, and part of another trademark. I don't have any problems as long as I don't try using it to sell juice. Or medical equipment.
There was a kid a few years ago called "Mike Rowe", though, who got in trouble by putting up a web page and calling it "MikeRoweSoft".
Then again, I can't imagine a company better equipped to go to war over trademarks than Apple.
