First of all, online literature has a more free and open creative environment, which can attract more potential authors to participate in it and meet the needs of readers for diversified and novel works. Secondly, the communication channels and carriers of online literature are very convenient, which can be read and exchanged on various terminal devices, and users can obtain their interested content anytime and anywhere, which greatly facilitates users' reading and sharing.
As for the best online articles I have seen, my answer may not represent everyone's choice, because aesthetics and preferences are very subjective. But I can say that I appreciate some excellent online works, such as Full-time Master, Natural Selection and The Longest Day in Chang 'an. These works have unique charm in different aspects, and I was deeply impressed by their excellent plots, characterization and writing style.
