Looking at the data dump for the recently closed Freelancers Stack Exchange beta, I note the license.txt file reads:
So let me clarify what we mean by attribution. If you republish this content, we require that you:
- Visually indicate that the content is from Stack Overflow, Stack Overflow Meta, Server Fault, or Super User in some way. It doesn#t have to be obnoxious; a discreet text blurb is fine.
Since this is in the clarification part of the attribution requirement, rather than the license requirement itself (i.e., the assertion of CC-WIKI), the omission of any reference to the Stack Exchange 2.0 sites is a minor point, but it might suggest to pernickety readers that the wrong license text has been bundled.
