"as many have noted", I suppose.
replyI'm always baffled at how many people write "of" instead of "have", they don't even sound the same
The classic one is "should have" or "should've" to "should of" because when spoken, it really does sound similar. I don't know what the fuck people are learning in English classes these days though, or if they even still have them.
replyThey sound exactly the same to me.
replyWiktionary gives <should've> as /ˈʃʊdəv/, unstressed <have> as /(h)əv/ and unstressed <of> as /əv/.
