I believe the biggest change would be to the newest members that would not know what the old IQ was like to be able to tell the difference.
This is similar to children growing up today that think Television was always color, CDs are old technology (What is an LP or 8 Track????) lol
I remember when my dad used to record us on his tape recorder, you had to put on a real of tape thread it though to a blank real it had 4 tracks on each tape. Of course this can still be found in music recording but these were actually the standard family recorders everyone had one even though they were as big as a small suit case! lol
My first PC worked on DOS, windows didn't even exist then! Nor did the internet even, oh what change a few years makes.
So I do not think the newest people just joining the new IQ would understand what it was like for us on the old IQ. But at least when the old is gone we the loyal from the beginning will have the memory of what it was like.
On the plus side Simon says the new IQ will be better.
