Steam != The internet. No one is preventing people from marketing their crappy games on their own. I have to dig through a mountain of shit in hopes of _possibly_ finding something worth playing. It's bad for users.
>my point is that you should maintain openness while making it easier to discover good content.
Well, figure that one out and I'm sure you'll make a lot of money. Until that happens though, I'll take a semi-closed Steam ecosystem instead of the alternative.
I'm not proposing solutions. I'm saying that "restrict publication" does not follow from "I'm seeing low quality content".
Don't restrict other people for your own benefit. Instead a solution that lets them do their thing while you get the content you want is much more equitable.
Why? The internet itself is an open, uncurated platform.
The basic ability to publish things and finding good content are two separate problems. Don't try to solve one by restricting the other.
