Kevin Rose, founder of Digg, has decided to shut down Oink, the first app from his new company, Milk. On March 31st, the app will be closed down after just over four months. Oink was downloaded over 100,000 times in it’s first three weeks. In just over a month, it had reached 150,000 downloads. The Milk team put a message on the site to users saying, “So long and thanks for all the Oinks! More news from us soon.”

According to Rose, the new service had tracked hundreds of thousands of Oinks and had over 40,000 active users. Oink allowed users to rate and rank things. Rose and the Milk team called the app a ratings engine for the things inside, not just the places on the web. The Oink app was all about gathering data.

Critics are wondering how users may respond to the quick closing of the app since it was so focused on data gathering and hope users won’t be apprehensive to try any new apps from Milk. There will be plenty of questions for Kevin next month when he will be at The Next Web Conference 2012 in Amsterdam.
