It's cool; we can let a small, overworked group of people who may or may not actually be very knowledgeable in that subject peer review it first. Might as well keep the data private forever too because reproducing the work might show something different.

I was up too late and grumpy, but the peer review process (while necessary) does prevent good papers from being published in a reasonable time frame. And acceptance is closer to random than you might expect.

Stuff like arXiv is in theory very good for the actual process of science, but so is having free, accessible journals and those don't necessarily exist in every field.
