It really depends on the business. There are a couple of local businesses here that I follow: a liquor store, a crepe cart, a coffee shop, etc. They all regularly post with specials, events, new dishes/type of coffee/beer, etc. YMMV, but knowing that I can pick up grilled fig, honey and goat cheese crepes on the way to work tomorrow is pretty cool in my book.

Though I imagine most pages are not quite so well utilized. These are all small, local businesses.
