Portside aims to provide varied material of interest to people on the left that will help them to interpret the world, and to change it.
There are Portside subscribers in more than 70 countries, about 90% in the United States (we think).
Portside subscribers seem to be a very diverse lot, geographically, occupationally and professionally, age-wise, racially, ethnically and otherwise. Also very politically active and opinionated, which counts as a good thing here.
