Google News has several such 'genre' tags. Flayrah uses them, too; pieces tagged as announcements or newsletters get "(press release)", reviews and interviews are marked as "opinion", while opinion gets "OpEd". Material from In-Fur-Nation is listed as "(blog)", and get a syndication-source header - though I'm not sure how much worth it has as they're not in Google News themselves.
