Thing 9 Technorati

Exploring Technorati among others to find feeds. Well, I looked around technorati and saw their catagories of what they offer. Interesting, but still I wonder does anyone care? Who has time to read all of these posts? I saw green solar feeds, technology and even celebrity gossip that I could subscribe to. I seriously don't have the time to give it more than a one over glance. I think it might be nice to keep them all in one place, but like filing... do we ever really go back to it? Any answers?
