I generally like the plan. Some post specific feedback though, it took me a couple reads to get that you meant NON-hive things and sending your payout to them as donation with a hive shoutout and a why I sent this to get your attention type note or conversation or chat or paypal memo or whatever on it.
It wasn't immediately clear and I was first going to respond with well, ya know, beneficiaries make that... then I got it. It's a neat idea. I wonder if a post can generate enough attention and income to make it noticeable to an outsider, and likewise find enough people interested inside hive to support the post in general depending on the post's topic/recipient and their interest level in it/them.
But lets say why not? its an interesting promotional approach to try. The only other concern being, hey outsider, I, a well known person with reach like BitCoinMan made a post on this thing and people used this thing to give me money and Im giving that money to you! Here's $2.73 USD! Now for you to get $2.73, you would have to go through some technical hoops, come here, build a presence and produce things and then people might give you crypto you can turn into some USD or a bunch of other things like having voting power, ok now let me explain that, and ....
so in summary. I genuinely dig the idea. I also genuinely wonder about its efficacy, but its certainly not harmful and would be harmless to try!
