Ok - so what is the big deal?
Well everyone has to answer this for themselves, for me it's unforgeable currencies, which looks like a big deal. That's why I pay attention, collect coins, follow alts, etc.
The coin didn't fork - it continues to be mined and traded.
These two statements are unrelated. Any fork can be mined and traded, this doesn't mean other forks don't exist.
Start your other coin separately.
Not sure what you mean here. Woodcoin reference perhaps?
Honestly - do you really think people cared about the whole 42 coin cap thing? Quite the gimmick, like so many alt coins.
Because nobody has responded otherwise, this is a confirmation of your statement. Indeed, nobody cares about the total money supply!!
This example doesn't bode so well for a 21million BTC cap on mainnet bitcoin does it.
Edit: well perhaps the market showed some signs of caring
