X announced that new comment sorting options would be introduced to enhance user experience, such that comments can easily be sorted by most relevant, most recent, and most liked. This solves the problem of managing replies to large accounts.

Now, for high-reach accounts, a comment thread in the thousands can be unwieldy. Besides, sorting better organizes the system and makes it easier to navigate. By offering these sorting choices, X aims to improve comment visibility.
The newest and most liked sorting methods let the user engagement shine through more clearly, but X has not yet clarified how exactly it will choose the “top replies,” for example. This might influence users’ opinions on what top replies are relevant.
Although minor in the details involved in the relevance, the new sorting features are supposed to serve improved interaction. More specifically, this update features an improvement in the manner comments likely to have a set audience are more easily visible to the user. This feature began to roll out over this past weekend, improving the experience.
All in all, the new sorting features make it easy for users to manage and view their replies. User needs and better platform experience have been carried out through advanced organization of comments.
