After considering a variety of different responses, some direct and some indirect, I've decided to heed the advice of the flightless one.
OP, as well as any other new users:
There is a lot of experience and a lot of information on this board. While many people come to ARFCOM with a pretty good base of knowledge and experience before becoming a member of our online community - there is still a lot of wisdom in the "read more, post less" philosophy.
At the end of the day, anyone can "claim" any amount of experience in a single internet forum post. I myself am a career Delta Team 6 Ranger CIA SAD Sniper JTAC with 1,337 confirmed kills from Vietnam to Canada... oops, I wasn't supposed to tell you about that last one. Also, you might not know it, but I am actually a founding member of the "Carbine Class Coalition," and invented not only direct gas impingement, but gas in general. I swear! You can believe me, it's on the internet, and it's not depraved pornography, so it must be the truth! I'd prove it to you, but my DD214 got lost in the famous records fire, and I signed an above top secret non-disclosure agreement that's binding, not only for me, but for my children's chidlren's children, up to and including until the second coming. But I swear it's all true.
My point is, I can type whatever I want - but part of what you get from "read more, post less" is that you have an opportunity to actually "get to know" who some of the posters are, whether or not you might ever meet them in person - and once you've read enough, it's not hard to deceipher who actually has real world, practical experience and knowledge, and who is blowing hot air, and hiding behind one facade or another. While you can "fake" knowing what the hell you're talking about from one post to the next, it's far more difficult to keep it up and be consistent.
This is independant of both join dates and post counts as well - some people have racked up impressive post counts over the last decade in the GD, and don't know shit. Some people just joined, and only post once in a while, but almost every single post they make is a good, insightful, and valuable piece of information.
Any time you make a post on a public forum, the peanut gallery will invariably chime in. Sometimes you'll agree with them, sometimes you'll disagree with them - but they're still the peanut gallery. Anyone reading needs to learn to sift through who belongs to the peanut gallery, and who might actually have something useful to contribute. And sometimes you'll disagree with knowledgeable posters that have a history of well formed and researched opinions. It happens, not everyone will agree on everything. And everyone has biases - when you "read more" you'll learn what even the most knowledgeable posters' personal biases are, and it will help you to interpret their opinions and decide whether or not it applies to you.
There have been a lot of respondants in this thread with a lot of opinions. Take the time to see not only what was posted, but by whom. You sometimes find that it's a little more one-sided than what a first glance would originally suggest.
Anyways, that's my unsolicted two cents in the bottom of the wishing well, since no one will ever follow this advice, and we'll field these flare ups once a week every week in perpetuity.
