This is from Mike Flaminio's blog, and it's blowing my mind so I wanted to share. As far as I can tell this article has never been linked to HBT.

Mike has done a number of experiments on wort oxygenation with a dissolved O2 meter, and has come to the conclusion that the best way to achieve consistent oxygenation of 12 ppm is to give the fermenter's headspace a 1-2 second shot of 5 PSI oxygen, and stir for 30 seconds using a paint stirrer.
This not only looks to be a super efficient usage of oxygen, but also very fast. He also claims that using an oxygen stone yields very inconsistent results for the amount of dissolved oxygen. All in all a very interesting read.
