This infuriates me more than it probably should.
No, this infuriates you just the right amount (or not enough). These people aren't even "bouncing ideas", they're asking "how do I..." They provide nothing and actually create negative productivity: if they just did nothing, they'd add no value, but they actually take time and value away from people who would otherwise create actual value. They're mostly functionally illiterate - that's why they need you to read the documentation to them instead of just reading it themselves. They have massive ADD, so they can't concentrate on anything for more than 30 seconds, which is why they have to interrupt everybody around them.
