Abstract: Systems and methods for receiving information associated with posts to a social network are described. Posts may be associated with a location. Symbols, portions or posts, or multiple symbols may be shown on a client device in an area of a map indicating a location associated with a post. Posts may be represented by symbols, which may include shapes, and such shapes may include emojis. An amount of symbols, posts, or portions of posts displayed on a client device may be determined at least in part by an area of a map displayed on a client device.
