You should checkout SinglePlatform’s newly released Facebook tab made specifically for bars and restaurants. You can see an example of it on McFadden’s Las Vegas’ Fan Page.

SinglePlatform is a social media and marketing platform specifically for restaurants and bars, and we are already working with thousands of restaurants across the country. SinglePlatform provides bars and restaurants with one platform that enables bar to optimize their presence on the ever-changing web. This one portal allows establishments to manage their critical information (events, specials, games and menu items) from one location. The platform updates their own website, their mobile site, and is distributed, in real-time, to a variety of other sites (social media sites like Facebook, Twitter, Myspace, review sites such as Citysearch and Urban Spoon, and iPhone apps like Foursquare and Gowalla among others).

While the six you mentioned are the most common, I would argue that you have left out the most important one: lack of a social media plan. When I speak with bars and restaurants about their social media efforts often times, they think that posting is simply enough, that cannot be further from the truth.

I understand where you are coming from in the article, however i think you are looking at social media as being a short term phenomenon, which is by no means the case. Social media will continue to rise. It is imperative for bars and restaurants to enter the social media process now in Facebook, Twitter, Foursquare (which will surpass 2 million users this week) and begin this lifelong conversation with their customers.
