With regard to how prediction polls are displayed on LW, the predictions made by others should be hidden until a.) you yourself make a prediction or b.) you press a button (or something like that) to display the results without predicting.
Since the prediction polls aren't trying to be a prediction market, I would much rather they be hidden first to avoid being influenced.
We have a setting that allows you to view them exactly that way. But I think too large of a fraction of people reading LW posts are lurkers, and this means that I am hesitant. to force them to press an additional button for every poll, but it seems like a reasonable setting that allows some people to opt into that.
I read KatjaGrace's "Sleep math: red clay blue clay" post. In it, people used either spoiler blocks or ROT13 to obfuscate their answers. Which of the two approaches do you prefer? Personally, I like spoiler blocks more, since LessWrong doesn't have native support for ROT13 en/decryption.
Same, but it would be much better if it was accessible through the editor UI, I constantly forget how to apply it as it is now.
