I can't remember if this is a content thing or a code thing, but the "recent posts" badge on the right-hand side of http://opentochoice.stage.mozilla.com/en/ should contain the last few most-recent posts. (Hoping this is a tag thing; if not, I suck for not filing it until now!)
AFAIR, the post that show up there need to be tagged with "featured". http://viewvc.svn.mozilla.org/vc/projects/choice/trunk/wp-content/themes/mozilla_choice/componets/highlights.php?revision=63599&view=markup would seem to confirm that. And IIRC, we only need to tag the English posts. The box will show the links to the translated ones automatically.
I tagged "Someone right now is wondering, “what’s this browser screen?”" with the "featured" tag, and http://opentochoice.stage.mozilla.com/en/ http://opentochoice.stage.mozilla.com/es/ http://opentochoice.stage.mozilla.com/fr/ etc. Looks fixed :) We should still decide which posts are "featured" on prod. Jane?
