We all know it will never really die, people will be people and lazy individuals who run the conversation inside their heads and spit out size XS sentences from the "Awesome" to "Worst thing ever" in the most arrogant and non-informative fashion, but the speed that people think they impose on their own thoughts leads to , well, idiocy and essentially zero information exchange, plus, if you do value other people's opinion (and pretty soon you'll put less value into them, which is sad for everyone), hearing enough of this things might just get to you, and that is also sad.
