Ohhhhh I see what you're saying now.
So with your example, players are consuming content... They're playing a game. With hyperPad it's more to it than that. They have to actually use the app and create something. So right away it requires more involvement.
So a survey is ok in some situations. But depending on the stage of the beta. It's mainly use the app. And test the specific functions we've changed or features we've added. But really, we're just asking you to continue using the app and if it's broken then report it in the beta section of the forum (where you only have access to if you're taking part of the beta).
Also with the betas we're selective of who can take part. Because sometimes they're trying out new advanced features that a beginner wouldn't know how to use. Additionally. with the betas you can't share to the hub. So this adds an extra issue for some people.
The major issues we had with betas is that users were excited at first, but then they either don't install the beta, or don't install the following versions so we don't know if their issues are fixed.
As for incentives, we did reward all beta users with "Developer" tiers.
You're right that the betas feel like it requires more dedication. And I think only users who are experiencing issues will take it seriously enough to provide their feedback.
