So, you can pay Twitter for access, and people do just that. We pay quite a chunk of a money for a significant percentage of the global stream of Tweets, and we use that to do analytics and sell those analytics to customers. Now, we also pull data from thousands of other providers, so it's not like we have all of our eggs in one basket, but we have a great business going where twitter is a significant percentage of the total volume of our data. Twitter also has certain advantages as a data source that many other providers don't.
