In my mind (and I could of course be wrong) twitter is harmful to society. Any platform that has code "if isRepublican then x; else if isDemocrat then y" is going to be divisive. "if isJewish" "if isFemale". It so obvious that this will promote distrust and divisions. I hear one thing, you hear another.

So my question is whether my understanding of the effects of twitter is wrong. Or do you continue to use twitter because ..."

Really I just don't get it. People I respect - Paul Graham for one - continue to use twitter, so maybe I am just not understanding something.
