>From time to time people have asked here where Mahout is used in production -- in particular I have noticed questions about the recommendation engine. I can add one more to the list of examples: Mippin (mippin.com). It's a mostly-UK-based news aggregator and mobilizer. I was doing some actually unrelated biz dev work for them this summer and figured out they were using Mahout to produce recommended news sites. Happy surprise. So, I have extended my remit to enhance the recommendation engine.
I've spent some time learning from how they use the system and have (with their kind permission) added back enhancements that came from this. Anyway, chalk that up as another instance of Mahout in the real world, and, should anyone be pursuing a similar application, I (and the source code) have now internalized some enhancements that help this use case.
