It's super creepy, and I don't see how it fits with the site or the rest of the design.
I think it's meant to be the same symbol as the circular design around the figure in the top right of the page.
That's exactly why I used it. But I agree it may send the wrong message. In my original mockup I simply had the accepted answer background as a solid green.
Do you guys have any other suggestions? Keep in mind, it needs to be contained within a square shape, and easily identifiable, and not overwhelming the numbers on top of it.
I can always change it back to the solid green.
The design on the upper right actually comes really, and I mean REALLY close to the symbol for the triple Goddes in Wicca (the maiden, mother, and crone). Personally, I think it's beautiful, but question whether religious iconography is appropriate in this case. I like it, but it might offend some of various faiths when they find out what the three crescent moons often symbolize.
As for the biohazard symbol, I honestly think that should be changed. It's a warning sign, something with negative connotations, and I think the symbol for an answer should be a positive sign.
But I waited to say anything because I think the design for SF&F looks great overall and know it's taken a lot of work to create.
