Agree with Planet13's thought. I see my sites getting a natural and varied interlinking when citing other pages of the website as martinibuster suggested.
Don't forget an occasional link within the blog page's editorial content to external authority sources to reenforce the point the page is focused on.
As to staleness I get a Google alert within 5 minutes of most blog posts (Wordpress' blog ping). Do posts regularly to keep G's eye on you :-)
