Thanks for writing this. I downloaded the SmartCash wallet and am playing around with it. Got 20 SMART from the Twitter promotion and then practiced sending 10 of it to another wallet. Transaction was nearly instantaneous.
I'm trying CPU mining from the wallet now. Haven't been able to get sgminer to start on a desktop computer... maybe the AMD graphics card is too old.
Anyways, it's been fun. Thanks for your article on SmartCash. I'm looking forward to reading more of what you have to say.
