The metabox that Publicize adds to the Editor is pretty dated at this point, and doesn't fit as well as it could with the other UI elements in the Publish metabox.

Suggest

• add an icon
• use bolding consistently with other elements there
• use an Edit link
• iterate on the layout of the list of services; possibly small icons for each and indent them?

Also consider updating links that appear in here to run via Calypso rather than coming back to wp-admin.
