Just used the new button to share this story. Works like a charm :)

This is very cool resource, will add it to resources page on ManageWP.org for users who prefer sharing via Jetpack.

Just to comment on the article freshness, we launched an algorithm update recently that also adds a time-decay factor so you should be seeing only articles that are at most 2-3 days old, depending how well they do. Important thing is for new articles to get upvotes so they can push older out. Its a magic circle :)
