checking out my subscribed blogs

With all my new blogs coming to me via Google Reader, I realized that I don't really "read" the blogs but scan them.  I have never spent so much time just scanning info. I feel like I was getting all kinds of great information and interesting stuff but now that I think about it I couldn't tell anyone what I "learned".  I understand that I could pick out one post that interests me to read but currently I felt I wanted to keep searching for a better blog/post.
