 That's a great example and that's I think it's so interesting because Airbnb of course combines the data that they collect from all the people who either offer their places or want to stay in those places but as you just said the ability to use that kind of government data just tremendously maximizes and helps them optimize their business. We see when we look at businesses around the world I think also two patterns. One is very much like what you just described businesses that can use open data to do their business better. In other words they would still have a business if they didn't get any open government data but they can have a much better business with it. So we're seeing examples for for instance a lot of major retailers are using really sophisticated models now that include all kinds of things that affect their supply chain. It might be how weather patterns or you know different kinds of shipping patterns can affect how they get what they need and when they want to have certain kinds of items in stock and so on based on what they've discovered from analyzing data about buying patterns that are affected by these other variables. We're also seeing a lot of startups using open data in some creative ways and I think one really interesting example is what's happening around agriculture and you can see sort of the range of applications. So one end of the spectrum is the US company called the Climate Corporation which has become a major example of a very very successful open data business. They were sold to Monsanto a couple years ago for around a billion dollars and they've developed very very sophisticated ways of using satellite and other data for what they're calling precision agriculture right. So it's essentially figuring out how to give farmers and large agribusiness really sophisticated information about how to plant their crops what in what crops and what cycle based on all the stuff that they can get from earth observation. On the other hand you have companies like M Farm in Kenya or Farmer Line in Ghana that are delivering just more sort of bottom line information for farmers in those countries that they don't need to do it by laptop they can do it by cell phone but at that level as well that information can be very very helpful in a similar way.
