I just shared the above comment with my wife and we both agree that it is one of the wisest things we have heard today. Well done layer8 and may you be (voluntarily) slow on all your days!
Why do you want to inflict an annoyance and deliberately waste 0.1 seconds (or whatever amount you deem appropriate) of everybody's time? Slowness should be a deliberate, individual choice. I'd be happy if there was a global cfg variable in the OS or browser, where you indicate the amount of pointless, "feel-good" slowness you wish to have in your interactions with any UI element, then you can have your way while I have mine too. I want things as quick as possible so I can race to idle sooner!
