Beehaw is a quieter experience than most because it has narrower federation, but you do tend to get a better signal to noise ratio since you miss the spammier instances - I like it.
Beehaw also doesn’t federate downvotes which I think is an improvement.
Posting from a Beehaw account I think does have a psychological effect on me that causes me to naturally tone things down a bit. I think it’s been good for me.
