Important reminder:
@miriamrobern Always knew there was something inherently wrong with Scrum Sprints.
@TomF @miriamrobern Sprinting is still a useful technique when you're trying to get away from something.
@sgf @miriamrobern A human can't even out-sprint a rabbit.

@TomF @miriamrobern You don't have to be faster than the rabbit, you just have to avoid being the slowest human.

The obvious application of this to Scrum is left as an exercise for the reader ("In this essay, I will explain the 'Killer rabbit' metaphor for agile development...").
