Threatening to kill people isn't funny.
I'm guessing you don't see a lot of sitcoms like Silicon Valley, Big Bang Theory, or comedians like Luis C.K., Sara Silverman et. al. Which is tragic, because they are awesome.
Not, of course, to suggest I'm as funny as that (clearly), just someone who's providing observations on Sift from using it in real world production applications (unlike almost all of the posts above this one).
