Thanks for the lengthy reply ! Most of what you said didn't even come through my mind once when trying to find an answer. .com indeed sounds old nowadays while .io is more techy, the "input output" reference is what I had in mind too ! Didn't think about the other puns though, makes me reflect on how I've been pronouncing websites names my entire life lol. Once again, thanks ! Gave you the maximum upvote I could, hopefully Musing.io will soon have a way to reward good answers with more than just our own voting power.
