什麼是社會性軟體，它與其他軟體有什麼區別，不同的人有不同的角度，綜合起來，就可以繪的相對完整的概念。

Matt Jones:"Social software = software that『s better because there『s people there"

Ross Mayfield:"Social Software adapts to its environment, instead of requiring its environment to adapt to software."

Clay Shirky:"Social software treats triads of people differently than pairs" (on the idea that, polygon-count like, social systems can be broken down to triangles, but no further) or "Social software treats groups as first-class objects in the system.", meaning that IM that only works point-to-point doesn『t count, but 3-way or more IM does.

Rich Persaud:"Social Software can be defined as software whose current output is organized by negotiation with at least one input that was not determined by the current user."

Sunir Shah:Simply put, I think only a definition heavily weighted on the human side with only a light touch from the technical side will be the correct one, as the fundamental imperative of this software comes from human nature, not from the technical sphere.

Stewart Butterfield :"Social software ... is software that people use to interact with other people, employing some combination of the following five devices: (1) Identity, (2) Presence, (3) Relationships, (4) Conversations, (5) Groups."

Stowe Boyd :"Social software is based on the person first, and the social group second -- the group arising from the interactions of individuals. People exist as individuals -- with their own interests, biases, and connections. These are reflected in social relationships, from which groups emerge."

Lee LeFever :Where normal software links people to the inner workings of a computer or network, social software links people to the inner workings of each other『s thoughts, feelings and opinions.
