The group operation has experienced three stages: single output, limited interaction, depth of participation.1, a single information output conventional practice is to invite big names to do sharing, limit the user to speak, the formation of a large number of WeChat groups, such as the early insertion of the sitting College, Steamed Buns Business School, it is through the WeChat group to do free sharing to get ten million fans, from a single group live to multi-group broadcasting has also given birth to the small U Butler such a tool-based company, allowing the Thousands of groups live to become possible. For a while, the WeChat group to do a thousand group sharing has become a trend. Later slowly we all know this play, all swarm to do weibo group sharing, but the user's fragmented time is limited, the user accepts the amount of information overload, at this time the birth of a thousand chat, lychee microclasses such companies, they parasitic in the weibo ecosystem, and will share the scene from the weibo group cut to their own live platform, thus relieving the user to climb the building and the information to carry the psychological pressure. 2, limited time Interaction If a single media-style operation will only make the community operation more and more passive, and even ultimately let the community die, then time-limited interaction of this operation means can improve the number of community user interaction, and can make the user more clearly understand their own purpose and original intention, but also to the community initiator operation points out the direction of the advantages of it is that it can occupy the user modular fragmentation of time through the phases of time-limited operation of the practice of the Users connect with the community initiator to a deeper degree. The community initiator has gained fans, and the community users have grown up.
