＂The development of writing and the visual organization of life made possible the discovery of individualism，introspection and so on．＂  Similarly，blog cause people to dig the deep heart，to discovered the real heart，and help changing or persisting．Physiologically，man in the normal use of technology（or his variously extended body）is perpetually modified by it． With long time managing blog，people are very easy to discover selves＇thought stereotype，to find the superiority and the flaw, and to analyse mind deeply．Earnestly looking at our blog，each record，each spoor，we may not help to ask ourselves＂why I always think by this way？Am I jumped into a circle？＂．We can be suddenly enlighted As a matter of fact，my thought follow such logic at all time．As the case stands, I care such aspect continuously． Our these characteristics which seems easily to find，without the helping of blog，will be difficult to find．That is to say，we always feel following some specific direction which we can’t say clearly，make evidently．However
，with blog，the illegible thing become clearly in front of us，our thought have extended and no longer merge into one organic whole with ourselves．In this electric age we see ourselves being translated more and more into the form of information，moving toward the technological extension of consciousness．That is what is meant when we say that we daily know more and more about man．We mean that we can translate more and mire of ourselves into other forms of expression that exceed ourselves． According precisely this truth，it is much easier to know ourselves after blog，Whether it is worth celebrating and cheering？

In any case，as the the extensions of thought，blog truly let us be infatuated, and bring joy to us．Just like the Greek mythology essence which Mcluhan explained men at once become fascinated by any extension of themselves in any material other than themselves．  We once have own blog and earnestly manage it，will certainly come into an infinite attachment．When usually obtain any new knowledge, have any feelings, bourgeon some kind of emotion, we will immediately bethink of blog．This phenomenon is natural in fact，because blog is our thought extending．When one appreciating oneself’s blog repeatedly, often can not releasing the eye for enjoying the content，and will not be willing to leave．At this moment，one’s the attachment regarding blog(think extending) are showing incisively．

In the electric age we wear all mankind as our skin．  This kind of analogy is appropriate，is rousing．Step into the internet，we are fused with universe．Theoretically speaking, we may find colorful and myriad thought in blog, what are the extensions of all the people on the world，which will be huge wealth for us．In mental，we will have more partners, friends, bosom friends；In the study, the work, the life aspect, we will obtain more inspirations and help；We will have more joyful which come from every corners；our view will be broadened largely；Our ability of understanding will be improved to an scale have not been arrived... ...and all of these will be specific and vivid，and will be got without attention，that because，all of these come from his，your and my blog—the extensions of his，your and my thought．
