From the whitepaper:

When you reply to someone else, they get 50% of any payout you receive in that thread. This rule applies up to 6 levels deep.

Here's how I see it. Imagine that I got $100 worth of upvotes and that you and bendjmiller222 made $0 from direct upvotes. Then, from what I understand, I'd get paid $53.33, you'd get $26.66 from your comment here, bendjmiller222 would make $13.33 and you'd make $6.66 for your OP.

outdated. I asked ned the other day, comments keep the full reward

OK great! One more question. Is there a difference for being the first to upvote content that becomes very popular into the thousands of dollars vs the second or third? Example someone posts content and you vote it up and it goes on to 10,000 dollars. Does your curation reward have to do with your steempower or is it based on a different calculation? And if the first two people to upvote were minnows with the same sp would the they both receive the same curation or the second slightly less? I'll try to look it up if you are unsure but I figured I'd at least ask. And now I'll let you get to answering others questions so I don't dominate the response field too much. You have been a great help.

I guess there are only some minor differences :)
