If you click on the "Amazon Kindle Social Network" link, in the following sentence,
We have an Amazon Kindle Social Network and wanted to supplement it with a wiki that anyone can edit and that would function as a storehouse of information. The primary purpose is FAQ, Tips and Guides. However, feel free to add on whatever you like.
it takes you to
http://www.booksummit.com/
which is the webpage for
"Kindle Forum Kindle 2.0 Social Network"
which is another Kindle discussions forum.
So no, it has nothing to do with Amazon.
