That damned Twitter :

''Researchers say that we need to be quiet and attentive if we want to tap into our deeper emotions. 'If we're constantly interrupted and distracted, we kind of short-circuit our empathy. If you dampen empathy and you encourage the immediate expression of whatever is in your mind, you get a lot of nastiness that wouldn't have occurred before.''

Some people are just arseholes, whether they use Twitter or not. But not all arseholes on Twitter stay arseholes, some discover the things they think & believe are not all that attractive to others, and if they stay and want to communicate, they bend to apparently acceptable norms.

Then again, some raging fucksticks are beyond all hope. And other Twitterers often tell them so. Sometimes it impacts, sometimes it doesn't.
