SteamOS, Linux, and Steam Machines
I feel like Valve has certainly been putting effort into Linux, but not serious effort.They seem to be going low-moderate risk/investment.  Sure there's progress, but then the Wine devs are moving pretty steadily too at the moment.If Valve wants to really be serious:- Offer incentives to Devs to support Linux/Vulkan- Release a goddamn new game (HL3 - dreams) and make it Linux exclusive for a time- develop and release new features for Linux first (maybe if GoG ever get the Galaxy client over to Linux Valve will get a kick in the pants to act...)- Promote SteamOS and (maybe) Steam Machines, like at least some.  Show Steam Machines as an 'out-of-the-box Windows gaming replacement, not a console competitor.- Fund Linux devs or take a lower cut from Linux releases- Convince Adobe to release their suite on Linux!  Push for/fund official Unity and Unreal Engine Linux versions- Offer the ability to natively launch games through Wine (and either use 'community' environment files or require one exist, or have a link to WineHQ for help)Be serious Valve, be genuine and get your flat structured 'follow the shiny thing' company focused and determined.
