Best Social Networking Tools for Online Startup

My client is an online restaurant plate review start-up in the Seattle area. I believe the best social media tools for them will be Facebook, YouTube, and Twitter. With Facebook they can utilize WOMM by linking their mobile app to Facebook status updates when a Facebook user rates a menu item. This should be optional, but it would be similar to checking into a location and allow people to share their favorite meals with friends.

With YouTube my client could show demos of the mobile app and how it can be used at restaurants. They could then post these on their www site and a Facebook fan page. They can use Twitter to announce new features and functionality of the app and also create hashtags for people to follow who are looking for top rates plates in a local area. They can also use shortlinks on Twitter to connect people to restaurant reviews or showcase new discounted menu items for pre-purchase before someone goes to a restaurant.
