HangingChad writes: Roger Thompson describes on his blog, also reported here, an experience that may point to banks and credit card companies aggregating data from social media sites. Before the corporate apologists step up with their usual "if you don't want to make it public don't post it" line, think about that for a second. And ask what's next? Are they going to start reading your email? Logging your cell phone calls? Is social media a public web site, or a convenient way to keep in touch with family and friends and where do we draw the line on corporate data aggregation? I'm thinking right here might be a good place.
