Some thoughts of mine:
I would say we mustn't forget that the site is community driven and should therefore blog about the community itself and how it evolves.
I've stumbled across a few users who were really friendly, really eager to become active, came to to the chat and even immediately thought about writing their own blog posts. We should give those (new) people an outlet to tell us more about themselves and how they intend to make the site better.
Also, it would be nice to address current changes, for example the "free downvotes on questions" and how the change impacts on the dynamics of the site. At least I'm very interested in the social behavior around the whole SO network and we at SU have the advantage of a smaller community. I really liked posts like How to get your questions answered? and their likes. Discussions on meta are a good read, but they're not that public. And I came to SO/SU for this very system.
