That's the power behind a tool like Facebook Connect. It is making a Web without walls. Facebook allows you to go to other sites to comment, rate, etc., without having to set up a new profile for that site.

Social media has made the web all about me, me, me.

You can spend your time daydreaming or make use of it in other ways.

Thank you for making a web site for me. I was so surprised when I found it.

Web sites get hacked so frequently, probably 50 a day, and if a hacker breaks into a Web site, they can easily change the code on the site, so that when users go to the site they think it's a legitimate Web site, and they will get infected.

The power of social media is it forces necessary change.
