Is there a plugin that allows for peer review of articles before you post them? IE, like a professional writer would send their work to a friend or editor to review and comment on their work before publishing it.

a pretty good explanation of what I’m trying to explain.
The most comprehensive editorial system for wordpress I’ve found is “Edit Flow”
http://wordpress.org/extend/plugins/edit-flow/
Adds extensive post statuses, an independent editorial commenting and messaging system, and much more…
Article you linked to describes more of a third party service rather than plugin.
WordPress allows to preview drafts. You can create accounts for friends/editors and send them preview link. Can probably be coded up a little for extra convenience, but as I see it could work just fine even with native functionality.
Author hReview
Add hReview and AggregateRating support based on schema.org, which help you increase search traffic by making SERP results more eye-catching. This plugin supports only the editorial ratings submission (edito/author rating), this means customers and site visitors are not involved in the rating or review process, this means rating reflects only the author’s opinion.
