Tech Tips Everyone Should Know

10) Maintain Some Privacy on Facebook

"Friend" is a loose term online. You may not want every random dude you're linked with on Facebook to know everything about you. So start a true friends list. Start on the "Friends" page of your profile. In the upper-left, click "Make a new list" and add your real-life pals to it. Then, in the upper-right of the page, hover over "Settings," click "Privacy Settings," select "Profile," and use the drop-down lists to determine which of your life's details certain people find out. If you want only close buddies to see those incriminating party pics, select "Customize," choose "Some Friends" and enter the name of the list with your "real" compadres.
