I have searching about SNS so far. Firstly, I investigated about the beginning of SNS. Secondly, I studied about the spread terms of SNS. Thirdly, I examined the development terms of SNS. Forth, I look into the present of SNS. That is, I inquire into the history of SNS so far. I have checking out a lot of information of SNS. Because of it, I have known various knowledges of SNS that I did not know. SNS is relation with us more than I thought.
Finally, I would like to look over and write down the after of SNS. One side mixi was defeated by GREE although increased the number of membership. So, recently mixi is trying to revenge to GREE by connecting with Asia countries. The other side GREE won to mixi with a full of game and so on. It is very interesting how GREE increase the number of membership without game user.
Many specialists are attention to the facebook and twitter. They pay attention the functions different from before functions. First point is easy to contribute. For example blog need the sense of sentence. And formal web sites need the technique of building software. That is, mixi and GREE are not useful for a corporate body. However, facebook or twitter can send message easily.
Second point is opening. Twitter can do closing and blocking. And facebook can do not consent the offer of friendship. And modern SNS is very openly than before. Because of it, it feels very relieved. And, a lot of value is easy to share by many people.
Third point twitter and facebook can easy to spread. This is very big characteristic.
By thinking about these things, facebook or twitter are declined to continue so long time. However, lately ten years, there is not SNS sites that were fashion other than yahoo and google. After of one year, new SNS site is declined to appear. And it stands twitter and facebook.
To conclude, present is not time that compete with the number of membership or sales volume. The number of contribute, relationship for example fiends, maimiku and follower and valuation for example iine or Re:tweet will be important in the future.
It is all my opinion, thank you.
