That's not the worst idea on here. I have no idea how much Patreon and various crowdfunding sites take in, but scale those up to Twitter's audience (which has some meaningful overlap with those likely to use or benefit from those services) and they get the foundation for a payment/micropayment type model. Twitter tried doing this with some sort of direct commerce experiment, but "give $5 to a cause/artist/politician" tends to be a more social activity than going right after retail, or hoping to crack the micropayments for content nut.

So reddit gold.

How's that working for reddit?

I didn't know about Reddit Gold and don't use Reddit enough to answer this.

Even if mechanism is same, I think result will be different for Twitter.
