Legitimately, I ignored this button for the last however many years until now.
As of five minutes ago when I checked to see what this button actually does, when you type in a search query on Google.com and press the I’m Feeling Lucky button it’ll actually just send you to the first result on the page.
Meaning, you could either find exactly what you’re looking for, or be so off-base that it’s just another thing for you to re-do in your life.
I guess the question is, do you generally feel lucky?
