My only experience with GoGuardian, to date, is a group of middle schoolers simmering Friday about their privacy being invaded. They may have a point, though their arguments aren't fully formed yet. One student asked if I could give him a quotation about GoGuardian for an article he plans to contribute to a digital 'zine he self-publishes with classmates. "A quotation about what?" I asked. "What's the story you're covering -- your angle? What questions are you seeking answers to?" At that point, the unplanned interview fizzled.
Here's a question for you, though: Anyone else have slice-of-life experiences with GoGuardian, or comparable programs, to share -- good, bad, or otherwise?
