A blog (from "web blog") is a discussion or informational site consisting of discrete entries ("posts") typically displayed newest first. All Corrente posts are front-paged; there is no up-rate or down-rate process. Corrente posts are almost entirely community moderated. We encourage a clash of ideas, and do not encourage a clash of persons.
