.... it's a forum. It's not like this is the "suggestions" thread where everyone's supposed to post suggestions, or the "questions" thread where everyone's supposed to post questions.
I'm pretty sure Steve doesn't say "oh I'll spend an hour replying to questions instead of working on the game", he probably checks the forum in his free time, etc, and I'm pretty sure he knows what suggestions are feasible for now and for later and to filter out the suggestions to leave for later.
What's the purpose of a "suggestions" and a "questions" thread if they were empty?
I understand you're irritated, but this is probably another way for people to express their excitement.
