What is this?

I googled my blog name to see how easily someone could find it. Surprisingly it did come up, but in this site called technorati. I'm not quite sure I understand that site. They're saying I should claim my blog so I can make a profile? But I can do that here on Blogger. Why would I need to do it elsewhere? Is someone else going to claim it as their own if I don't? That wouldn't be right. Someone else trying to claim my life?!
