Correct, it is one part but with 5 million units or so sold to date on that platform and the daily activity on its forums for Ark being arguably as or more active than the official forums, here, (I've not monitored reddit's activity to state otherwise). I understand the statements of foucs on reddit and the official forums but its somewhat counterintuitive knowing how steam makes for quicker facilitation of dissemination of information by just under half the player base of the game.
Also, I know members of the team have expressed as well open disdain for the steam forums too in the past but again its just a shame that resources cannot be put forward on the platform more to have both proactive and reactive responses to issues and interactions. While you cite the dev team being small(70's if I remember right), that doesn't require precluding more volunteer mods answering to Eli, you, etc or even some non dev team related payment resource that could be allotted for more liasons for steam either. GP Deb David are the only volunteer mods typically witnessed sporadically on steam ark forums and I think you can agree you could well enact more and quite easily.
So again its just disappointing I genuinely think more could be done and not require full time devs at WA/FL/UK paygrades to do it. There are not too many things I am overly critical of the team for but the reticence to facilitate more on the steam platform in these regards is one of them.
