Um...
1. You can get your story featured if it's good enough to deserve said high rating, and featuring gives you points, so this would be a bit redundant. Besides, just creating your first three games give you points to begin with. Besides, getting a game to be well liked by your fellow writers / readers is its own reward.
2. No. No, it would not. Have you ever seen the comment section of a busy youtube live stream? It's trollish nonsense and utter chaos. The people who have anything important to say, or have real needs, get ignored in favor of the loudest and rudest of the bunch, or alternatively, get steam rolled by the enthusiasm of the masses. We've had hundreds of guests here before at one time, I do not need or want to know what hundreds, or even 85 (the amount online currently) people are thinking all at the same time. That's what would make telepathy, a theoretically awesome super power, total hell. If it was an open chat for, say, 10 people at most, fine. Maybe even 20. But a site-wide real-time chat would be madness, and we have forums which are open to everyone, just slower and well-monitored.
