Oink is a mobile/social discovery service that was named one of Business Insider's Top 20 Startups of 2011. What does it do? Basically, it is like Yelp, Foursquare, or any other app that lets you discover local places.
What makes Oink different, however, is that it lets users not only discover local places but the things inside them too. Users can rate anything that is around them, from a latte to a piano to a video game, and build up cred in the areas that they are most active in. The app is similar to Quipster in that way, allowing users to gain influence in the areas that most interest them.
The most attractive aspect of this platform is its flexibility. It appeals to people with a range of interests - not just food or drinks. However, platforms with a more specialized focus can target a more specific audience, potentially making it easier to build a strong user base.
While Oink probably won't take the spotlight from the likes of Yelp, it is definitely worth checking out if you're an iPhone user interested in discovering fascinating things around you. Oink is holding a number of contests throughout the year, so make sure to keep up with their blog and check out the app!
