I don't think attendees should get anything. Instead, the funds should go to server costs and to compensate the ones who use their spare time to publish the material, that is @cm-steem and @peppernrino.

While it would be neat to get greater attendance, attendee reward isn't going to attract the crowd we want. Remember that this is currently a fairly niche topic. You have to have discoverered BOINC, be into cryptocurrencies AND be curious enough to dig into the news channels to find that there is a hangout (or podcast). Maybe we should see it more as an open podcast. Once the listener count increases I'm convinced that so will the attendee counts.
