Wow. That is incredibly half-assed considering how important it should be.

The contrast with twitch's system or with patreon or kickstarter could not be larger.

Out of curiosity, what does Twitch do differently than this?

They have a big sub button, and give streamers tools to modify the experience for subs. You can give them sub only emotes that they can use everywhere, or you could put your chat in sub only mode, or you could make recorded videos that are sub only.

Even that is not coming close to realizing the potential of such crowdfunding, but it beats a random tip button that sometimes doesn't even show up.

well to be fair subscriptions != donations
