To me it doesn't matter much what the forum platform software is. The bigger problem is whether there's regular moderation and involvement from the people tasked with running the forum. There's not a lot of that here at all.
But, this is just my guess, I think this forum platform is temporary. I think at some point the "Community" will be developed directly into the app, not just as a link that takes you out to a web page.
I say I "think" but what I really mean is I hope. The entire Stadia buildup was about connecting people and building up a special gaming and media community. If that's the case, I am hoping they have a plan to integrate the Community forum in a way that it's accessible directly within the app, whether on phone, PC or even Chromecast.
Stadia sold a big picture of providing a platform where the entire world could be entertained... together. If they really are going to go after that, having the Community forum as a separate, standalone entity doesn't make sense.
Like I said, it's just a guess. I'm not a developer, social media wizard, marketer or any of that. But if I was, that's the kind of team I'd be trying to build to handle the community aspect of Stadia.
