Information Overload?

Information consumption is becoming a chore to me. We are expected to blog, tweet, post facebook statuses, etc. Then we consume others' blogs, tweets, posts, etc. And this ranges from our friends, associates, acquaintances, famous people, friends of friends', associates of associates', down to any random guys. And all this is in addition to our other searches for information through the web. There should be a research that confirms that it is not physically humanly possible for us to keep sane with all this information, without having a life outside of iPhone, iPac, BB, and PCs.
