How many years is the google search engine? I think I've been using since it's very inception back when. Mostly because I completely despised the then Web Portal (and directory) approach to search engines.
... and yet... If I say I clicked the I'm Feeling Lucky search button 3 times in all this time, I may be overstating.
I've just realized that with Google Instant, clicking that button is impossible! As soon as you begin to type, it changes the page and removes the button. I can see why they'd want to get rid of it, then.
Actually it used to be there with Google Instant. It's not anymore. Didn't notice that change until you mentioned it. Smart of them. Possibly a 2 step plan; First make people forget about it, then quietly remove it. Better than just removing it and facing a barrage of criticism by folks who... actually never used it, or don't care
Really! Weird! They probably thought it was depleting your "life energy" or something like that. Some of the stuff they thought back in the old days seems pretty far-out now. Breath was your soul. Illness was caused by magic spells and curses (witches, wizards, etc ...). That was before they came up with germ theory. Hmm. What else?
