A good Facebook App Developer (<- immodest link) can tell you that the newsfeed is a Facebook basic. The newsfeed is where users first encounter an app, even before they get an invite.

As Facebook expands the newsfeed, it’s very good news for developers who make quality applications. The team is letting users vote on news items.

Thank goodness.

Sorry Zombies. We don’t anticipate you showing up in the newsfeed after a few more weeks. Useful apps, however- ones that announce a basic action or an interesting interaction- will continue to get play. The ones that just show spam won’t be as lucky.
