Well, Satoshi doesn't think 0 confirmations isn't that bad. So why should we be more concerned than the almighty creator of bitcoin!?
If you're requiring more than 0 confirmations, it's nice if you show the current balance (0 confirmations) and the available balance (1 or more confirmations), so they can immediately see that their payment is acknowledged. Not all sites need to wait for confirmations, so the dual current & available should be optional. Most sites selling digital goods are fine to accept 0 confirmations.
That means a lot coming from you
Thanks Satoshi. You've always got my back.
