On the website, there is a flexible subscription system: currently, users can subscribe not only to the entire site and all posts from it, but can also choose specific categories they want to see in their "My Feed" and receive notifications for each category. With this approach, you can get a snapshot of the feed - by fact of publishing a new post, as well as group and receive notifications in the feed or in a separate category of new posts. 

We continue to form a unified chronological feed, so that there is no algorithm for the formation of the feed, and users themselves can choose what they want to read.
