Japanese vs American Twitter

One of the cooler trends on Twitter recently has been the whole Japanese x American cultural exchange, which I've found very revealing in terms of the main differences between the two cultures.

The Japanese mainly seem to use Twitter to discuss culture, food, art, share anecdotes and stories, get nostalgic, and keep up with the other 95% of totally normal interests that are never mentioned on American Twitter-- and if they were to be mentioned, it would be with scornful disdain, as if those things were inferior activities (cuz people who regularly fry their brains with digital opium are too joyless to derive any pleasure from daily life).

I also saw very little political content-- and even the stuff I saw wasn't extreme, deranged, weird, deliberately gatekept, etc, it was all just reasonable stuff anyone could agree with. Not meant to be offensive or triggering. 

This more normal focus ties into another trend I noticed, which was the total lack of irony, the widespread sincere tone, and the eagerness to please and interact in a friendly way with the other side on their behalf. It was very refreshing, and at the same time could not be more opposite of  how things are done in America.

The way it works here is that everyone just hides their feelings all the time, through a kind of ironic numbness, and so most people never really express anything.  The actually sincere people-- the ones who are willing to open up, show their feelings, and make an effort-- are a tiny minority of the population, including on the Internet, and to make things worse are always on the defensive, because there's a kind of seething bitter hater type (and general impulse in the culture) to tone-police any display of emotion, in order to maintain peak irony and hostility. 

This results in a situation where the best you can hope for on most forums, websites, sub-cultures, etc is just an environment of atomized neutrality, where people refrain from witch-hunting and cancelling each other, but otherwise don't form real connections (since doing so would violate the rule against showing any emotion)-- and at worst, as everyone knows, seething hatred, pile-ons, neverending witch-hunts, etc. 

I know that it's a very downer thing to say, and I don't mean to shit on American / Western culture so much in the midst of something positive like this, but it really does make me bitter about how sterile, anti-social, and hostile our culture has become.
