July 20, 2010, 4:48 PM — If you're like other U.S. Facebook users., you probably spend a good chunk of your online time aimlessly browsing wall posts, photo albums and playing games-seven hours a month, to be exact, according to a Nielsen report.
But all that time spent on Facebook doesn't have to amount to nothing. Within Facebook's hundreds of applications and add-ons are a handful of useful ones that let you connect and collaborate with others more easily -- and even help you rationalize your Facebook browsing habits. Check out these four cool Facebook tools.
The BlackBerry PIN Exchange is an easy way to share your BlackBerry Messenger PIN on your profile, browse your friends' PINs, find new friends to connect with via your BlackBerry and more. Worried about sharing too much information on Facebook? Solid privacy settings give you control over who sees your PIN and where it appears.
Back in April, Facebook and Microsoft teamed up to release Docs, a new way to collaborate and work with your Facebook friends. Similar to Google Docs, Docs lets you browse, create and share Microsoft Office documents with your Facebook friends. You can upload a file, choose additional users who can modify the file and publish it to your activity stream (if you'd like) so your spreadsheet, document or presentation is visible to your network.
