I think this is the way to go—but a CC attribtuion license is very different from an assignment of intellectual property (in a good way!) - you will need to provide attribtution on the about page and any subsequent usage of the entry for one thing (the whole point of an attribution licenese is to protect those moral rights!). so you should update your faq to reflect this.
Just changed it to a Creative Commons Attribution 4.0 International License, so posting it elsewhere is fine (or even encouraged).
