That's ok, as adoption continues to speed up, the network effect will take hold. It is only a matter of time, and the adoption rate IS increasing. This is due to not only merchants, but users adopting it.

Once a user has the wallet and Bitcoin, they can send each other money, as well as buy from merchants. Believe me, when they begin to understand they are in essence, their own bank..they will realize they are saving money on fees, and it will explode in usage exponentially.

Also, Bitcoin is also a payment network, not just a currency. There are many reasons why it is superior to other payment networks, which will further drive adolption.
