I think the PerchApp.com would be a really valuable tool for your readers and contacts. Its free.
Perch is a smartphone app that enables you to monitor the social media activity of your competitors so you can trump them in real time.
The app gathers the Facebook posts, Yelp reviews, tweets and Internet deals of other businesses and streams them to your phone. If you see a competitor offering a deal, you can counter with a deal of your own."
Forbes has called Perch, "The Must Have App for Small Business."
