I’ve written several posts on using Facebook in a ministry setting and the privacy issues for personal use. Click the ‘social media’ category at the right to see what I’ve said before. For another perspective on the Facebook privacy issues, see a post at ULVOG DOT COM, by my cousin Christian Ulvog.
His post concentrates on the frequent changes to privacy settings at Facebook and the difficulty of customizing the settings based on your wishes. A few recent changes have made data public that people thought would be private.
As John Bredehoft pointed out, it is their home and they can set the rules as they wish. To extend that idea, Christian’s wish is that we could each build our own house and set the rules there as we wish.
