Over the years I have had really nice interactions and disasters with Noobs so I tend to give them the benefit of the doubt and focus on the content of their posts. I only factor in post count when it relates to a potential trade or sale - not that I refuse to do business with nephytes but I do proceed more cautiously. Too many people who quickly come on the forums are looking for the instant gratification and don't understand the limitations and difficulties with reps and how things can go wrong or they are not perfect. They think they are buying gens and expect gen-like perfection and even service. They also don't know the rules of the road. Having said that I have seen many quality people come (and go) who do have something to add - whether simply friendship or knowledge. I also expect the vast majority of noobs to disappear for any number of reasons - just looking for the best rep of something, has other things to do, just doesn't take to the whole hobby, etc.
