For me, the first step to getting any kind of support and cooperation from Valve, is to fix the clear issue that exists with regards to communication.
Somehow we need to get them conversing with us and the overall community much more often and much more candidly. A proper two-way discourse (and not just us complaining, as we often do).
Once we get proper communication, I think it's much easier to show them our world, and they'd be more receptive to showing us theirs; their challenges, problems, thoughts and ideas. Once we know what we're working with, we can move forward in the best manner and imo this would infinitely help the situation.
Probably the only way it can be solved is through the more known members of the community leveraging whatever contacts they have in order to set up a discussion with Valve, specifically about the communication issue.
Maybe Valve fears getting our hopes up, maybe Valve feels there isn't the money in it, maybe they are unaware at the harm that a lack of communication does, maybe they're not interested, or maybe they don't know how. The problem is, we haven't a clue. I think the community/comp community needs a closer working relationship with Valve if anything is to get done long term.
