Apart from recent redesign complaints, Facebook is more popular than ever, boasting over 100 million users active at the site every day. That's great news for Facebook, but it also means that the social networking site is more of a productivity sink than ever. If your in box is full of tagged photo notifications, friend requests, and status replies, head over to Facebook's Notifications settings to set a more manageable flow. If you still want to receive all the alerts but you don't want them cluttering your in box, check out NutshellMail , a free service that sends you a digest of your Facebook activity on a schedule you determine.
