I recall a conversation I had with Steve Sinofsky, back when he was in charge of Windows. As you might expect, he gets to see early versions of a lot of things, his laptop is running dogfood everything, and everybody is asking for feedback.
And he rarely gives any.¹
Not because he's a jerk, but because he understands that if he provides any feedback, it will get magnified from an idea to a suggestion to a recommendation to a direct order.²
"Why isn't there a Frobnicate button right next to the Widget? The main reason I go to that page is to find a Widget to frobnicate."
This becomes "Steve wants to add a Frobnicate button right next to the Widget", and then "Steve says we have to add a Frobnicate button right next to the Widget".
I guess, if he is moved to make a suggestion or share an idea, he can mention it to somebody and add "Tell the XYZ team, but don't tell them it came from me." I don't know if that's what he actually does.
¹ Presumably he gives feedback on the functionality as a whole, but today I'm talking about feedback on the level of feature requests or tweaks, like how the UI should be laid out, or the order of the pages in a wizard, or whether a wizard should be used at all.
² I hesitate to mention that at the time Exchange was being developed, the Ctrl+F standard did not yet exist. Try it: Fire up your archived copy of Windows 95, launch Notepad or Wordpad or whatever, and hit Ctrl+F. Nothing happens. At the time, the standard hotkey for Find was F3. (And, in fact, many applications today still accept F3 as a shortcut for Find.)
