Here's another great idea from Google:
1. Create a slew of broken results through a cocked-up algo update,
2.. Run a whole series of UI tests on said broken results.
Barry lists three and I just found another minor UI change being tested:
That makes at least 4 spotted in the wild already.
A multitude of UI tests being carried out while a broken algo is still running?
Puh-lease. Someone donate a brain cell to help Google out. The world's brightest boffins have no common sense.
