A large part of "LittleBigPlanet" is the global community features through the PlayStation Network for the player to interact and share their "patches"—levels and other modifications—as well as online play. As of September 2011, more than 5 million user-created levels have been published. The main focus of the "Share" component is the ability for level creators to publish their levels and objects to the online community for other people to play. Once a custom level has been played through, the player can tag the level with a list of predefined words and may cycle through the word choice to find the most appropriate. This allows other players to quickly find their level of choice. The player can search by a specific tag such as "Beautiful". The player has a "heart" feature available to them, which allows them to specify which levels, stickers and decorations they prefer; in this way, people can heart to show appreciation for other people's creations, and visit their online friend's hearted items, or visit the creator of a hearted item, then view his or her hearted items, and so on.
