So, I really don't know, but it strikes me as dumber than a box of rocks. Are we all somehow welded more closely together? Are we shown as harmless? Are linguistic fads just so cozy? Is silence really that frightening? Does it make anyone sound smarter, less abrasive, more caring, more thoughtful ... more ... so ... je ne sais quoi?
In a world reeling with dumb, it just seems a pity to add to another snippet.
So ... so ... so I'd better get my act together.
