Is "weak copyleft" not comparable to the LGPL? LGPL appears to have a
place; why not "weak copyleft"?

At the risk of being stoned... yeah.
I just don't consider an article that uses a photograph of mine as
illustration to be a a derivative of my work.
I don't want an article, blog or book author to have to license their
whole text under CC-BY-SA just because they use my image.
HOWEVER, I do want them to be obliged to make explicit the license of
my work, that is offer it to others under the same conditions. My
work, not theirs. That is how I think "weak copyleft" differs from
CC-BY or PD.

So "weak copyleft", if we are talking about the same thing, suits me well.

Brianna
