This was raised as one of the topics on the general question dealing with site design.
I'm not sure we have arrived at any sort of consensus. So I'd like to clarify the matters via a separate question.
Are we as a community in agreement with using the BioHazard-like symbol to denote questions in the list that have an accepted answer?
Personally, I dislike it on both design and aesthetic grounds - my favorite design among SE sites for this element is the solid dark block on StackOverflow. The main problems that I see with this one is:
The color is too pale and close to background color - hard to clearly distinguish accepted ones at a glance
The bulk of the picture is in the center - both obscured by and interefering with - the count of the answers.
IMHO, the image is not very pleasing visually. I realize that this isn't actually a biohazard but some Wikkanish design, but I can't help but be reminded of some ID software game with biohazard barrels.
