Is this why privacy wasn't included in the Bill of Rights?

The purpose of this blog is not as much to inform as it is more of a general inquiry.

We are all in agreement that social media has changed a lot of things in the world. But I can't seem to figure out how. It seems like before Myspace and Facebook first hit the internet, everyone wanted their privacy. Everyone seemed a little timid to give out any information on the internet.

So what changed? Rather than keeping to themselves, people now send updates via twitter every few hours to let the entire world know what happens to them. Most the time the stuff doesn't even matter anyways. People post pictures and videos from every aspect of their lives. And nearly anyone can look at these things. Sure, they have blocks and security features, but there are always flaws in the system.

Is this uniting society? Or drawing us apart? While we all meet at the same place, none of us are physically there. Maybe it is simply because the benefits finally outweigh the risks.

Any thoughts?
