Hi,
David Vasquez has spent the last few weeks refining the Wikinews logo to address the concerns of those who voted against it in the logo contest. See:
http://meta.wikimedia.org/wiki/Wikinews_logo_contest_voting/Variants
for the process. Primarily, he has tried to make the logo more distinct from that of the United Nations, to avoid potential trademark/copyright problems or simple confusion. I've gone ahead and replaced the logo that is currently in use with one of the updated versions (except on those editions that use a logo with custom text; I ask those to please modify theirs accordingly). The differences are small, but should help to give us a more distinct look and feel.
Please do continue to comment on the above page, and help us to refine the logo further.
All best,
Erik
