Marco-
Erik, I haven't seen a comment from you about this
so far, but I would be
very interested how you want to solve these problems.
See my response to Brion:

Specifically note that textual quotes are already a form of fair use, and
more closely linked to the actual article text than images. You don't want
to forbid us to quote Martin Luther King, do you?
Regards,
Erik
