The plugin is very cool. You simply author the post as you normally would. You click a 'lil button that says "Review this Post"... and all kinds of valuable goodness auto-populates the post.
For instance if I name a place, say Ann Arbor, MI, that'll be auto-detected and linked to...
If I mention a company, say Hewlett-Packard, then that too will generate goodness (I've opted for the badge at left...)
You can read more about it (and get it for yourself) here....
