that 0.02 upvote may actually be worth a lot of money some day. (Seriously.)
Yes, when I look at someone's decent post that earns $0.20, I remind myself that someday that may be $20... or $200. And if I upvote that to $0.24, I've just increased that by $4... or $40! Looking at the future value can have an affect on how we look at these pay outs today.
This post is worth over $1000... or $10K That's $7.41 per word or more!
