For example, the account that you create to use Microsoft Zune by default displays your name,  your location, your bio, the names of your friends, any comments left for you or by you, and your recent music played to everyone.  If you have an XBox Live account, Zune Social will import all of your XBox friends. Imagine your prospective employer googling your name to find out you have a friend named “PooBurgler.”  That said, you may want to share all of this information – I personally don’t mind sharing it with the world – but you may also want to set this to Friends Only. To get to your profile, click on your name in the upper right corner of your Zune window, then select “zune.net Profile”. You can probably also login at social.zune.net.

Pandora by default will allow your Facebook friends to be able to see (and listen to) your playlist titles. Again, maybe not a big deal, but I was surprised to be able to see this information and even more surprised to find out that one of my dear friends has a Vanilla Ice station.  You can disable the sharing of your information by clicking here and then Disconnect from Facebook. If the prior link does not work, click on Account on the Pandora page, then click Sharing, and finally Disconnect from Facebook.

iTunes does not yet have any privacy issues that I’m aware of, but the much anticipated social media functions iTunes are coming soon.
