In the vein of speaking about things one is to be irrationally annoyed by, I absolutely, positively [i]loathe[/i] the style of those who send multiple single sentence and or limited word responses in any medium in rapid succession. It boggles my mind how anyone can live by writing or typing an utterance or two, sending it, then repeating that process three or four times. For God's sake, use sentences and paragraphs; they exist for a reason! Worse yet, this often means messenger devices will incessantly sound their notification that a message was received, making this even more annoying by introducing an auditory or vibrating component that gives the impression something important is taking place.

I suppose this goes in step with my dislike of media devices at large, particularly phones. The rule goes, unless it is absolutely pressing and urgent, say that someone is dying, something that cannot be awaited on in reply like an email, never, and I do mean [i]never[/i], am I to be called by phone. There are few things worse in their level of disproportionate distraction than a ringing, noisy phone, only for it to be a call that serves no purpose.
