(1) The influence of network technology and resources on online comment writing. As far as the technical conditions of online writing are concerned, online comments may put background information and detailed concepts into the second and third layers of "hypertext" writing, and add non-text materials such as audio and pictures. Some scholars believe that this is the development trend of online comments, which can accommodate information that cannot be accommodated due to traditional composition restrictions. This process is not so much a process of "writing" as a process of "editing" the "pure text" of one's own work according to the communication characteristics of the Internet. With the prosperity of blog writing, it has become possible to comment on the author's own direct "hypertext writing", because the blog is the author's own space, and he can use any conditions provided by the blog to set the expression effect of his own text.

In online comments, we often find that some authors will consciously segment in time, and some will almost segment sentence by sentence like poetry, all for the convenience of readers. This awareness of "attention resources" is often due to the writing of comments in paper media and the influence of network communication environment on the structure of comments.

(2) The influence of reading rhythm on the topic selection of online reviews under the network environment. Online reading is regarded by some scholars as "a high-cost fast-food reading". Because the audience and reading rhythm of online reading are different from traditional media, the requirements of topic selection, writing style and timeliness of online comments will be different. Generally speaking, online reading is more urgent than paper reading, not more leisurely, so some "cold" topics that are calmly discussed and some topics that are more deeply thought about often have lower click-through rates.

(3) The influence of online interpersonal environment on online comment style. Because online readers are generally younger and freer-thinking, the style of online comments requires more liveliness, more direct expression and even more intense, rather than stability and ambiguity.

The network environment has a far-reaching influence on comment writing because it directly faces anonymous criticism. This kind of criticism can sometimes be very sharp, which requires writers to have higher tolerance and broad mind. Some authors can't stand sharp criticism and can't help arguing with anonymous critics, which not only does not help people to accept their views, but also damages the image and power of comments. At the same time, due to direct feedback from readers, and mostly anonymous feedback, the elite consciousness of a commentator who publishes articles in newspapers and periodicals will naturally be constrained, and a person's tone of voice will have more room, and criticism and rebuttal will be taken into account.
