You're right - and I think this is a common failure mode of the population at large, but my most common failure mode is not finding something in a quick google search then failing to just ask someone else who probably knows while either wasting too much time searching or giving up. At the risk of the typical mind fallacy, perhaps this is the most common failure mode of the average LW member as well. If the grandparent could somehow be changed to target people like me better, I think that would improve it the most.
