I would enjoy having a more friendly discussion environment, but I don't want to make it a duty. I mean, offenses are bad, but mere "lack of warmth" is normal, although it is nice to do better than this. Among men, this is often the normal mode of speech; among women it's usually otherwise... I think it would be nice to let everyone speak in their preferred voice. We should encourage men to display more warmth (and it would be an interesting topic on how to do it without feeling awkward), but not criticize them for failing to reach the level convenient for women.

I think it would be useful for someone who finds niceness natural to do a post how the average LW can build affordance for being nice, preferably in a way that doesn't add to much noise. I also think it would be good if people were motivated to use some of these affordances due to genuine niceness/to help build the community.

On the other hand I strongly agree that having a "nice" voice should not be even quasi-required. Fake/forced niceness often feels phony in an unpleasant way, furthermore forcing people to change their conversational voice seems like making them jump though hoops. Also, I suspect that people who have a naturally nice voice underestimate how hard it is for people who don't have a naturally nice voice to talk nicely, even when they want to (this is based on super-high priors for this general form of fail happening any time the opportunity presents it self).
