The one that I'm worried about is the phrase build upon this work. If I find an answer to my problem that includes a code snippet, and I use that snippet (or some part of it, or something based on it) in my code, do I now have to release my code under "the same or similar license to [cc-wiki]"?
If so, doesn't that mean that code provided in answers on Stack Overflow should never be used in non-copyleft code?
