Reddit
Site overview
As a network of communities, Reddit's core content consists of posts from its users. Users can comment on others' posts to continue the conversation. A key feature to Reddit is that users can cast positive or negative votes, called upvotes and downvotes respectively, for each post and comment on the site. The number of upvotes or downvotes determines the posts' visibility on the site, so the most popular content is displayed to the most people. Users can also earn "karma" for their posts and comments, which reflects the user's standing within the community and their contributions to Reddit.
