Many of the social phenomena that take place on-line can be usefully interpreted in terms of status, power, and the mechanisms by which people evaluate and form opinions about each other. In this talk, we discuss a set of approaches for measuring status, ranging from metrics based on contributions to subtle signals in the language people use when they interact with one another. In addition, we also consider ways in which the allocation of status can provide incentives that shape the collective work of a community; surprisingly, we find that in theoretical models of effort by credit-seeking individuals, certain unfair assignments of status produce incentives that can lead to increased productivity.

The talk includes joint work with Ashton Anderson, Cristian Danescu-Niculescu-Mizil, Dan Huttenlocher, Lillian Lee, Jure Leskovec, Sigal Oren, and Bo Pang.
