网络文化具有的交互性、开放性、多元性、共享性、虚拟性特征,构成了一种新型的网络民主。而虚拟实践中人的主体性困境:一方面是人在赛博空间中新的人生体验和自由拓展,另一方面是人沉迷在虚拟世界中迷失自我、意义空虚。本文指出网络社会必须寻求虚拟现实与现实世界之间的平衡,防范网络的时空延伸而意义萎缩。 Network culture has the characteristics of interaction, openness, diversity, sharing and virtuality, forming a new type of network democracy. In the virtual practice, the subjectivity dilemma of human beings is that on the one hand, people experience new life and develop freely in cyberspace. On the other hand, they are addicted to losing themselves in the virtual world, and have an empty meaning. This paper points out that the Internet society must seek the balance between the virtual reality and the real world and prevent the meaning of the network from shrinking in time and space.
