I think this is a good idea. It's not totally dissimilar to some things I've mentioned lately, but you make it sound less like you're about to seize the means of production or bring in the sort of income redistribution that gives voluntaryists nightmares. Anyway, I'd certainly be in favour of some mechanism to donate to @teamaustralia if that meant bigger upvotes, free drinks and contributing to charities.

If could play devil's advocate for a moment, I suspect this could be a little complicated. For example, if there's more than one #teamaustralia post, which one donates the SBD? Would I be committed to this? I'd be happy to hand over my normal earnings from one post, but if something I tagged with #teamaustralia got a vote from @curie or some whale, handing over that much money might sting a bit.

And that's just people acting in good faith. Someone less scrupulous might just try make sure that their nominated post earned less than their average. But that opens us up to being arbiters of what constitutes a post of acceptable 'quality'.

I'm sure we can iron out the bugs though. If it didn't cost an extra 5% I'd consider using the beneficiaries feature in SteemPlus - I could just send a set percentage of a post's payout straight to @teamaustralia - though I think it's only SP - you'd have to ask @stoodkev about it.

Either way, I'll make sure my next Australian-themed/related post has the #TeamAustralia tag, and I'll endeavour to kick in some SBD (not like it's worth that much right now anyway).
