There is a problem with CC-BY - in that derivative works may have to include the names of all people who worked on the piece - unless the contributor agreement is worded correctly.
This is the advantage of the new Creative Commons wiki license -- it allows the attribution requirement to be satisfied by attribution to the wiki rather than all the individual contributors.
The Creative Commons wiki license was created in response to my suggestions and my explanation of what is generally considered acceptable to the community with GNU FDL. It's an attempt to encode what are already wiki best practices.
