The one thing I don't like about blogs is that so many of them are "me " centered. I realize they are supposed to be like a journal of daily happenings in a writer's life, but written journals are usually private.
I kept a diary (or journal), from the age of 12 until I was 20. I think I did it because I liked being able to go back in my life and see if and how I'd changed as a person -- my opinions about people, movies, events. Interestingly enough I stopped keeping a journal about a year after I met my husband -to-be. Just lost interest. Imagine every single day for 8 years I wrote in my diary. Perhaps I just wanted to record what were my first impressions of the man I would marry. I know I just lost interest in journaling once I knew we would marry. Interestingly too, I just recently went back and destroyed all my old diaries. Believe me there was nothing earth shaking in them. I'm 69 now and I don't want anyone else reading all that teenage nonsense!
I do like keeping track of my friends by blogs, and I did learn about ATC's through blogs, but so many I've read just promote" what a wonderful person I am" or "how sorry you must feel for me". Your real friends are interested in that, but casual readers like me are just hoping to broaden their horizons a little, I think. But then again, I don't open up easily to people, and I don't think people are all that interested in my daily ups and downs, so I'd rather write about concrete things. It is nice to be able to share a little about things you have created or new things in your life that someone else might identify with.
