In my previous post, I talked about the limits on sizes of tightly-knit communities. These group limits are closely related to a number of interesting personal limits, and are often confused with them. Unlike the group limits, personal limits actually measure something different: the number of connections that an individual can hold. They're yet another thing that you must consider when thinking about communities of people. Personal Limits The Support Circle: This is the number of individuals that you seek advice, support, or help from in times of severe emotional or financial stress.
