Depends on the community. I've met some very helpful noob-friendly developers who recognize you're a noob and will use simpler terms to guide you through the process, and passive aggressive assholes that'll ignore your messages the very second they figure out you're a noob. Even though they were literally just talking to you seconds before.
As long as they don't F up the price of the Steam Machine, then this would be wonderful for both the gaming and Linux communities.
Good news! They made things worst a few days ago by requiring users to request permission to get a personal API key. So if you don't already use a modified 3rd party app with your own API key, then you're fucked!
