TIP 6 – Avoid accidentally sharing personal details:
You wouldn't put a note on your front door stating, "Away for the weekend...Returning on Monday." Micro-blogging tools like Twitter and What are you doing right now? features in Facebook, LinkedIn and other social networking sites make it easy to let details slip that you wouldn't otherwise broadcast (to friends or strangers). Be aware of what information you put out there which others might use for nefarious purposes.
