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 hereby pre-commit to finishing and uploading my post on Lojban by 2359h Thursday, my local time. It will cover the basics of Lojban grammar, as well as what I like and dislike about the way it is designed.
