This seems like a really neat idea. I'd be happy to do a short (20 second) survey to get access to content. I'd much prefer to do a short survey than watch some of the pointless stupid annoying ads that Youtube is giving me at the moment. And there's little chance of me taking year subs for all the sites I read maybe once a week.

Survata should be aware that any longer than that, or poor content hidden behind the survey-wall, means that I'm likely to just click random options on the survey. But I'm sure they are.

Good Luck to them!

Really, someone 'just' needs to fix micropayments.
