"I think this is getting needlessly messianic." ~Fook
Having more than two options clouded the issue of actually determining what the majority may have wanted. We can't actually interpret much from the hidden or visible vote. We don't really know what the last two options mean in terms of hidden or visible in general.
I trust WT Sharpe, our messiah, to make a decision for us. I might disagree with their choice, but an Internet forum isn't a democracy and I don't expect it to be.
For transparency, I voted other and I made a joke about a convoluted visibility scheme because I don't actually care what the voting is for hidden/visible. I'd like multiple choice options because it might more accurately show which books are most likely to be read by members. In the end whatever will get more members involved in nominations and in reading and discussing chosen books is good for the book club.
