With the development of media technology, everyone can speak. When individuals become
media and diaries become means of individual publicity, they often have strong conflicts with public
interests and media industry. To clarify the process of diary publicity is of great significance to
understand the boundaries of individual and public expression. The study found that the publicity of
“diary” can be divided into three periods: in the early period, the diary of heroes and great men were the
main ones, because the mainstream media endowed them with public value, which played an important
role in social construction; in the middle period, the diary was mainly made public by individuals,
and the “right maintenance” was carried out through the struggle of diary, which was easy to cause the
loss of social expectation and self worship; nowadays, the publicity of “diary” can be divided into three
periods The way of writing is to fight for the right to speak through “identity deviation”. This kind of
individual diary not only has an impact on the media industry, but also leads to difficulties in network
governance. Therefore, the public space should establish a multi content standard system, individuals
should strengthen self-discipline, and jointly build a good network social space.
