When is one no longer a newbie?
There's a caveat about Noobism that we must cover before going much further and that is the idea that everyone at one time is a Noob to everything. Believe it or not, this simply doesn't hold up because some of us are better at finding information and incorporating it into our skillsets. And other people could not find the broadside of the barn if the barn hit them in the face!!
I play MMORPGS from time to time on the interent whenever times are slow. The first thing I do is I read the Terms of Service [do YOU actually READ that???!!! ], followed by the manuals, the popup helpful hints screens, and then I look for the hints/FAQ/Guides sections, along with the FORUM! I might spend an hour doing this research, but by the end of this orientation I find I know more about the game and how to play it then some people who have been playing for months. The Noobs, meanwhile, sit on the global chat blasting the communtiy with these questions that make the thought of stabbing toothpicks through one's eyes to be a relieving sensation. There and in itself you have the definition of "Noob."
Noobs are too dumb to figure things out forthemselves. OK ok, I'm being harsh! Noobs have been too ENABLED by Others to Figure things out For themselves! THERE! By this mark I do not believe that noobism is based upon IQ or upon actual intelligence but by learned behavior. It is likely this behavior began when the person was young and someone else, frustrated in watching them struggle in learning how to figure things out on their own, simply gave them all the answers. I knew these kids in grammar school, because while they had all the answers on their homework, they had not a lightbulb behind their eyes when it came time to discuss the worksheets.
So you don't want to be a noob?
The first mark of noobism is a person who doesn't read directions and note the obvious conceptual details of their immediate surroundings. Want to appear noobish to a reference librarian/? Ask where the bathroom is. Seriously, it is suddenly very important to you, but if you look around in most libraries, there are very very plain signs pointing towards the bathrooms.
You can also spot a noob when it comes time to assemble a kit or a device. The noob reaches for the weird dangly sparkly object and the black bar and stare off into space as if they just got hit by the broadside of a barn. Obviously the parts aren't going to tell you how they go together...yet!! that would be funny, a kit that yells "PUT THAT DOWN!!!" when you pick up the wrong part one too many times out of sequence! So if you don't want to look like a Noob, reach for the instruction manual first and read it!
The final mark of noobism is to be hesitant to do ANYTHING at all until someone else tells you to do it. I realize in Kindergarten they taught this concept as a method to instill a Followship of students and "Following directions," but ultimately always waiting for some one else will simply induce a state of helplessness reliant upon someone bigger than you for instruction. Eventually there comes a day when you must embrace your own decisions and live with them, and for most of us that day comes when we become adults. For true noobs that days never comes. So if you don't want to be a noob, start doing and stop wallowing in self pity about your lack of innate knowledge about construction techniques, product quality, and material choices. You will figure that all out by jsut by doing for yourself!! Just don't be surprised if you build a module with ten different innovative designs in it only to discover that 1) someone else has done ALL of them, 2) ALL of them appear in the RR press and 3) EVERYBODY wants to talk to you about your innovative ballast work ["HUH???" you say? But that I just DID and it HAPPENED!!!!]
Now I read your comment about the NMRA MMR requirements being Draconian. Perhaps this comes as a misunderstanding that this scale measures all modelers, from the starter lightweight to the climber on top of the mountain. If you want a top of the mountain rating, you have to - well, CLIMB THE MOUNTAIN!!! That isn't Draconian, that is Experience! And no amount of "looking at pictures and describing that experience as if you were on the summit" isn't going to suffice as the same experience!
I realize that in a more politically correct world we have to take all of the climbers difficulties in mind, depending on their personal ability level, and by these weights and measures ALL climbers are equal. They both climb, right? So there's no need to introduce a class-level-rating competition becasue this is all for fun any way, RIGHT?? Sometimes trying to point out the obvious to these people can be quite a triteful experience of encoutnering human [counter?]intelligence!!!
Regardless, there are people who are more knowledgeable, more skillful, and destined to reach higher heights than you or me. The trick of the ticket it to STOP looking at THEM and START looking at YOURSELF against the standard - NOT the other people! You want to be the BEST model railroader you can possibly be? Then pick up those "Draconian" MMR requirements and challenge yourself to do complete the course. If you don't finish it in this decade, it should give you a good idea what you can and can't do today, and what you have to work towards in the future. And even if you don't ever finish the course, it will help you appreciate the work that goes on in this hobby and appreciate the people behind that work. You'll be far unnoobed for having attmpeted the course too!
That's my take on Noobism. It is a condition quite independent of the challenge, meaning some can people skip this level altogether. It's not a permanent condition but it can be dehabilitating if it is learned early and strongly reinforced. The only way to escape this level is to learn how to do for yourself - don't laugh, for some people this would be the equivalent of climbing the empire statebuilding in a helicoptor. But this skill is alone the most valuable skill any human can develop, so do not be so hasty to help someone Avoid the learning curve!.
