I'll acknowledge the fact that there are definitely details that ought to be ironed out and to be discussed, but it's the phrasing that you and Archmage used which to most of us seems more blunt than helpful. More bashing and forceful, than constructive criticism. Besides, the GM in question appears to be new on this site, so going entirely full hand as you've been doing can be rather off-putting. Perhaps if you guys said more regarding "Maybe you should concentrate on this and that..." or "I suggest maybe going more this route..." one question at a time, could the reception be treated better.

Perhaps what I said earlier may have been a little more aggressive than one ought to like, but nor does a person starting out have to be faced with a heavy hand themselves. That also doesn't necessarily help when there's someone I happen to... not quite like.

Because so far, from what I've seen, as well as from a few others here, ironically they've seemed to be both rather aggressive in your suggestions, good intentioned or not. And I'm not very keen on people with such behavior (blame experiences in other similar situations). 

Now could it be that I'm wrong to say that the GM has been discouraged because of this? Perhaps. I did mention he could be busy or he happened to have forgotten about the site, or perhaps something completely unexpected happened. In fact, I want my initial thoughts to be wrong. However, judging from what I've seen, there's enough evidence to place my current concern as a solid theory.

But again, I do acknowledge your concerns and I also agree more information ought to be provided. But don't overwhelm a newer GM with too many questions with a blunt after-taste. I believe the approach that [@jynmi88] provided is the better choice in this situation.
