The Collaborative Web

Web 2.0 (from Wikipedia):
The term Web 2.0 information sharing, interoperability, user-centered design,[1] and collaboration on the World Wide Web...Examples of Web 2.0 include social networking sites, blogs, wikis, video sharinghosted services, web applications, mashups and folksonomies.

Web 3.0: This idea is still forming. Some say it is just an extension of Web 2.0 with an emphasis on hand-held devices, like smart phones, and other devices. Others, including Tim Berners-Lee who was one of the inventors of the World Wide Web, say that Web 3.0 will mean a Semantic Web, or as its Wikipedia articles states, "a web of data that can be processed directly and indirectly by machines."
I guess time will tell.

How does the collaborative creation of content affect the evaluation of sources? How does it affect the authority of a source or the accuracy?

Take a thorough look at these two sources:
American Orchard
2. New Insight into the History of Domesticated Apple: Secondary Contribution of the European Wild Apple to the Genome of Cultivated Varieties

Write a paragraph comparing and contrasting the authority and accuracy of the two sources. Post your paragraph to Blackboard's discussion board. Use your CRAAP guidelines to guide Authority and Accuracy. Realize that the format of the source will play an important role in your evaluation.
