Scrabble knock-off Words with Friends is coming to Facebook today. Words with Friends is made by Zynga, the company behind Farmville, CityVille, FrontierVille and other online games.

From USA Today: "It really opens the game up to a massive audience that I don't think has played the game yet," said Paul Bettner, general manager for Zynga With Friends. "This is an opportunity to broaden the audience that can play the game by an order of magnitude."

Mobile Words with Friends players will be able to compete against Facebook users.
And, really obnoxious friends can use a "brag list" feature built into the Facebook version, to post high scores and big wins on their wall.

"Hey everyone! I played "Zebras" on a triple world and triple letter for 108 points!!!".
