Maybe Bitcoin will conquer the world, maybe it won't. I have no idea.
What I do know is there is real utility in being "electronic petty cash" which Bitcoin can easily become.
Imagine: Alice sends Bob a few bitcoins after Bob writes a particularly insightful comment on HN. Bob then comes across a great blog post by Charlie and sends him a few bitcoins. Charlie then finds an open-source project by Diane that will save him hours of work and sends her a few bitcoins. And so on.
It rarely would get converted to USD and wouldn't amount to much when it did. Instead, people would just earn a bit here and spend a bit here.
Bitcoin enthusiasts miss that USD works fine for most people. But right now it's really hard to do the above scenario using traditional banking. I don't want to connect my bank account to some website to send a someone a few bucks. It's just not worth the hassle/potential risk.
I can't be the first person to think of this. But I'm just not seeing much movement in this direction. Am I overlooking something? Or do I just need to be patient?
