Online privacy, and the data mining of companies and governments, is all over the news lately. But few realize the scope of data that is collected. In the fall, NPR did a series of stories on the information that is collection and how it can be used. You can read the first story in the series, "Your Digital Trail, And How It Can Be Used Against You" to see how every bit of our lives contains information that is mined by one entity or another, even if we don't realize it.
It is important to consider the information we present, or may present, to others online. It is also important to consider who may have access to that information. Though we cannot prevent the mining our information, awareness can help us be more proactive about what we do (or say) online.
