First of all, this can directly affect the person who has their information on the open web. This means that the person's reputation is greatly tarnished and the fact that they used that website will stay with the person forever. That person would have a harder time finding a job or could potentially get fired from their present one. And more importantly, any relationships would be severly strained if not completely broken.
Even though none of us has not used this website probably ever, there are many signs from this hack which affects us greatly. First, this shows us how even the most "secure" websites are not secure after all, which means that any information about us that we put online is open for hackers to look at. And since almost all of our information is "open" to look at, we have an increased risk of robbery, blackmail, and identity theft.
Personally, privacy means almost like secrecy, things I want to keep to myself or to certain people stays with those people. And that we have control of what information we want to give to others.
Simply put, I think the best way to protect ourselves from being hacked is by not putting anything about ourselves online. But if we do have to put some information about us online, it would only have to be information that we don't mind anyone else knowing. We can't even give it to reliable sources like banks or retail stores like Target without the possibility of getting hacked.
