facebook has introduced targeting options for posts to any page with 5,000 or more fans. probably not an immediate option for most SMB page owners, but hopefully the water will run downhill. let's call it aspiration for now... :)
If your page has more than 5,000 likes, here’s what the new feature looks like:
Page administrators can choose to target news feeds of specific types of user, based on categories such as gender, age, relationship status, education, interests, location and language. This does not affect what kinds of posts users will see when they visit the page (all of them), but rather which posts will show up in users’ news feeds.
