To answer your statements/questions:
I have done a lot of things to make FAF a better place (ie: improving the map generator, making maps, making mapping utilities, making new props, answering other questions, training noobs, working on code, etc), and it is obviously not realistic nor my job to respond to every random question asked on FAF.
I responded to Valki now (rather than earlier) because he directly invited me by name to respond to those posts yesterday (and not earlier)... I generally try to respond when someone basically asks me a question and @'s me, as I think that's the decent thing to do...
I imagine Morax feels similarly on the above, but I don't want to speak for him here.
Personally, I question the value of FTX's choice to shoot down most new ideas very readily. I think that policy makes negative associations with the FAF experience, contributes to a negative atmosphere, and discourages participation. I don't believe that attitude is good for fostering a collaborative and friendly atmosphere. There are many occasions in which I think the way FTX responds to people is worse than if he didn't respond at all.
