I love Coinbase's new auto-buy option when making a purchase. That'll certainly help.

I really don't buy much, and the gift card hoop jumping is just annoying - I've played with it but it takes a real effort.

When I can pay for gas at the pump with BTC...
When I can go to the supermarket and spend BTC...
and when local restaurants/bars/coffee shops are taking BTC...

then I will be spending BTC.
