Why do we read blogs?

It's an odd occurence today that blogs have a high level of poularity. But why do we feel compelled to read them?

It could be the sister's diary scenario. We want to be privy to some secret information about others. Know something about them that we wouldn't have learned through non-covert means. Once we learn this juicy tidbit we feel powerful and that makes us want to read more.

Or it could be that we want to feel secure that we are truly normal. We have our own set of experiences and ways of acting. How can we know if it is normal? Am I the only one who is interested in deep sea marine life (only an example) or am I the only one who eats a full, $1.29, 6 serving box of Mike & Ikes in one sitting (if only it were just an example). We long to feel normal and when we find someone who thinks the way we do we become elated. Finally, someone who shares my fear of roller coasters! These knowledge also forms a bond with the other person. Somehow, finding that other person justifies our actions. Now we can do them without shame and humiliation; bring our foibles out into the open. But not until we find that person.

Do you know why we read blogs?
