Rob,
I wouldn't put you in the rivet counter category at all. You have real knowledge of the subject you're commenting on. I don't mind constructive criticisms from you because I know they are coming from someone who knows and who is trying to be helpful, that's not a rivet counter to me, especially if I post something I am presenting as accurate. I don't have a clue about armor, so I expect and want some feedback when I'm bold enough to post one.
I have to admit, I'm one of the "good job" guys because I figure the builder has tried his best and is more critical than I am. They know what doesn't look good but I feel they need encouragement to continue to do better on each build. I should probably point things out, supposing that they didn't see the mistake themselves, but I just can't bring myself to do that, that's not me and that's OK. The world need all kinds. Too many people like me and we have the everybody gets a trophy scocity, too many the other way and most people would be too discouraged to continue..."why try?"
The world and every hobby NEEDS both, just not to the extreem either way.
Now like Forrest Gump would say "that's all I got to say about that"
