After beating Google for most web visits on Christmas Day, Facebook once again whooped up on Google on New Year's Day. Granted, the margin wasn't as large, but since Google is the clear winner every day, it's nice to see someone else wear the crown here and there.
Facebook is a great way to connect with a bunch of people all at once. Update your status with Happy New Year and it goes out to your entire network - family, friends, coworkers - whoever you've allowed in. It sure beats making a bunch of phone calls or sending a bunch of texts.
Ironically, it beats out sending a mass email. It's accepted on Facebook that your update is meant for your entire network while an email to a bunch of your contacts is just not cool.
