Possible opportunity for inbound marketing?

I have worked at a gourmet grocery store for almost over ten years. I have seen a lot of changes as they finally created a facebook, I glanced to see the work they have done. The facebook is mostly used to keep up on sales and special dates coming up. Until this class I have never thought about possibilities it could bring. Then I thought Why not twitter, Pinterest? with twitter they can keep updates, and possible monthly coupons for their twitter followers and it will be more mobile friendly. Throughout the store the have recipes posted why not Pinterest? If they use Pinterest this could increase searchability as well as a adwords account and analytics. This could bring great opportunity for the company itself and myself.
