I think integrating Reddcoin on Patreon would be a better marketing choice than using it as payment system on Steam (even though I did sign the petition). It leans more towards what Reddcoin wants to become.
I would start with integrating RDD to Patreon, because it has a wider range of content creators. Steam is mainly for gamers, while Patreon handles an income for all kinds of creators and artists. So the more kinds of creators we can reach, the more people we can reach to build up the Reddcoin tipping platform.
