Wikinomics Chapter 7: Wisdom and creativity of the crowd

Back to Wikinomics: in chapter 7 we're introduced the concept of companies opening up their platforms for others to modify and create other applications - mashups - by combining data with many sources. Perhaps the biggest challenges to this harnessing of the "wisdom of the crowd" are

1. Allowing "the most interesting applications" which tend to violate copyrights or the rights of the people whose data is being used.
2. Creating a business model that allows "the crowd" and/or its most productive members to share in the wealth.

Obviously, the crowd benefits from its own collective wisdom, but those especially productive members wonder if they shouldn't get more, somehow. I'm curious what has been done since this book was written to make some of these things happen. I know, for instance, that Flickr has teamed up with Getty Images in order for some Flickr contributors to have their photos marketed and perhaps licensed and make some money off of it.

Have you seen other ways that platforms have shared with the crowd? And how about all the apps now available for iPads, etc. Are any of those built by the crowd, bought by Apple? Any ideas?
