If I lift text from, e.g., someone's comment on meta.*.SE and stick it into *.SE/faq, do I have to either include the full attribution we generally require or get a waiver from the author, is a link to the original content enough, or can I just use it, assuming that's why people wrote it in meta?
My understanding, based on Jeff Atwood's writing, is that the original author owns the copyright and implicitly licenses it under cc-wiki to SE. cc-wiki requires attribution "in the manner specified by the author or licensor." That manner is specified here, and requires a decent amount of overhead. So, perhaps the author's implicit license to SE requires that manner, regardless of any implicit waiver from SE, and therefore would require waiver from the author to leave it out. On the other hand, perhaps submitting content on meta implicitly licenses it for use on that site's FAQ.
If SE has the power to waive [some] attribution requirements, does it in this case, either explicitly or implicitly?
