In recent years, Reddit has attracted the interest of many researchers due to its popularity all over the world. In this article, we aim at providing a contribution to the knowledge of this social network by investigating three of its aspects, interesting from the scientific viewpoint, and, at the same time, by analysing a large number of applications. In particular, we first propose a definition and an analysis of several stereotypes of both subreddits and authors. This analysis is coupled with the definition of three possible orthogonal taxonomies that help us to classify stereotypes in an appropriate way. Then, we investigate the possible existence of author assortativity in this social medium; specifically, we focus on co-posters, that is, authors who submitted posts on the same subreddit.

近年来，由于Reddit在全球范围内的流行，吸引了许多研究人员的兴趣。在本文中，我们旨在通过研究三个方面（从科学的角度来看很有趣），同时通过分析大量的应用程序来对该社交网络的知识做出贡献。特别是，我们首先提出一个定义和对子目录和作者的几种刻板印象的分析。该分析与三种可能的正交分类法的定义结合在一起，这有助于我们以适当的方式对构造型进行分类。然后，我们调查了这种社交媒体中作者分类的可能存在；具体来说，我们专注于共同发布者，即在同一subreddit上发表文章的作者。
