I tend to hold the view that there are three general types of beginner-level people in any given area.
1. Noobs/newbs. These folks do not take what they're doing seriously, make lots of mistakes while claiming it either didn't happen or was somehow not their fault, refuse to listen to instruction, tend to be very loudmouthed about what they think they know, and often present safety risks to those around them. They are arrogant, and are especially dangerous when they try to teach other people about what they think they know, especially because their arrogance is often mistaken as being confidence by those who know even less. Noob is a derogatory term, because nobody likes to be around that kind of person.
2. Newbie. The difference between this group and the last is all in the attitude. These folks tend to be more willing to learn, more willing to admit their mistakes, much softer spoken about topics they don't yet have business talking about, and are generally pleasant to be around and offer instruction to. Newbies are ALWAYS welcome, unless the mission of the group specifically requires experience the newbie doesn't yet have (competition shooting teams, etc.).
3. Amateurs/novices. These folks are just newbies who have a little experience under their belts, but take the field more seriously. They show serious interest, and are very conscientious of safety and learning. They aren't arrogant, but they are confident in what they've learned, while still being open and eager to learn more/better.
I consider myself pretty much a permanent amateur when it comes to firearms and shooting; at least, that's what I strive for. I like learning.
Don't be a noob
