From Wikigogy

Copyleft is the use of copyrights to empower open and fair collaboration by explicitly permitting modification, dissemination and reuse and ensuring these rights are not separated from the work.

Creative Commons Attribution-ShareAlike 3 keeps even Derived Work, for example that commercial interests may make of our Work, under the identical free license and thus available for us to bring a copy of back into Wikigogy and or commercialize if we wish. If a commercial interest can make a Work from Wikigogy better I would like them to as long as we can bring back a copy or even commercialize it further ourselves so that we have not set ourselves up for exploitation. And if a commercial interest can disseminate a Wikigogy Work I would like them to as long as they give attribution and share alike. "Share-alike" lets the Work have a life of its own while maintaining everyone's right to it; "by-attribution" helps the world learn about you and Wikigogy.

Commerce is a powerful life engine. Empower it.
