I think what would help indie/smaller games more than anything, would be a website that helps gamers looking for other gamers interested in certain games find each other.
Granted, we have a lot of those. I think ENWorld has a forum for gamers looking for groups, as does Roll20, etc. However, the problem is that indie games tend to have relatively small audiences to begin with. By spreading them out over dozens of different LFGs, you're either forcing them to post on dozens of sites (which, let's face it, nobody wants to do), or you're spreading them too thin among those sites, such that they'll be lucky to ever find each other.
What I'm thinking would be like the Facebook of LFG (in terms of popularity - practically no one uses MySpace anymore, and G+ died out). Of course, that's easier said than done. You'd need a robust site, and you'd probably need a significant amount of advertising to get it the traction it needs. Which is, again, easier said than done, especially since this site is unlikely to draw FB-like advertising revenue.
I think it's what the indie community could really use right now though. It's easier than ever to find a game, but because they're diffused among various sites, for an indie gamer it still isn't easy.
And to be clear, no, I'm not willing to implement it. But it's something I've been thinking about the past few days, largely as a result of this thread. I believe that the gamers are out there, at least in the majority of cases. It's just unreasonably challenging for them to find each other. That's something that the right technology with the proper traction could definitely help with.
