I think a big part of the problem is that a good portion of people are using the mobile version these days. When viewing this thread (or any poll thread) via mobile there is no option to vote or to even see the voting results thus far. Mobile users have to change views first, a lot of average everyday users probably dont realize this.
CFC made a post in the OD social about this thread, which is how I stumbled upon it since I don't normally walk these halls. I bet more than a few followed me here but I'm willing to bet 99% of them casual users who did couldn't figure out how to vote cause they are on mobile so they quickly gave up.
I'm excited for the change. I think it's definitely needed since the vast majority of the younger generations seem to use mobile devices more and more, some almost exclusively. There are too many problems with BL mobile experience (unable to edit posts without accidental delete, unable to edit profile, unable to vote in polls, unable to make posts in OD because they can't select a thread prefix, etc) so I fear we are turning away a lot of the younger generation since they are likely to get frustrated and give up.
How about 'Light and Dark'? Any subject is acceptable as long as it is significantly enhanced by natural or artificial lighting (or lack of). This could include lens flare, highlights, shadows, reflections, sun rays etc. (but no filters allowed). Perhaps the winner could be bestowed the title 'Lord of Light' ?
