Yes, "adding" anon is the flavor of the month.
If you read gmaxwell's complete destruction of the sub-optimal DRK anon approach...
You begin to realize that anon has to built-in from the ground up...
It's not something you just "tack on" later = common knowledge among Devs.
On the other hand:
(1) Anon may be VASTLY overrated...
Who cares about anon buying meals, cigs, booze, tickets...
And with cars, real estate you DON'T WANT anon... you want it registered.
(2) Yes, it all comes down to "good enough".
As for SC, the wallet is very nice...
But I would like an explanation why anyone needs a coin for social networking.
