It'd be nice if DGB hooks up with Steam then you have a real powerful gaming eco-system for DGB. Imagine this; people get payed for playing videogames which they can then use to buy games and related software/hardware on Steam, it's like a self-enforcing loop-system. The more people earn DGB's playing video games, the more they will buy gaming stuff using DGB, the more they will earn DGB etc. etc. Then people get accustomed to the idea of purchasing games and related stuff with DGB seeing it is more userfriendly compared to the more tradtional payment methods. So in short, I think DGB and Steam are a very good match.
It's really good idea. I suppose devs have plans already for steam.
