I expected people to care mostly about age, which is weird that they did not mention it. I was not quite sure about the post count. But in my opinion this is a useful poll because it shows what the attitude of the forum is rather then, what you rather have sort of thing. I'm glad that I did it though got a lot of unexpected results.
Well, age always play a part.
Generally, a 20yo will be more competent and serious than a 15yo. Then again, it can be completely opposite. You have kids at 15, who's been working on cars and learning from their dad for the last, well, the last 15 years really, and therefore know a lot about cars and mechanics. I am nearly 20, I'm 20 in April, in fact, and I don't know SQUAT about engines. Really, I'm as wise on engines as my mum.
Actually, I once had a moderator in my staff. 15yo guy, who made some money from stacking fish crates in a local fish plant up north. He was one of the most skillful forum members I have ever come across. He knew his shit, and he was as serious, actually more serious than most people in their 20s. Does that make for evidence that 15yos are better members than 20yos? Not at all, but it does prove that what's the rule isn't always what's true.
But in the end, you can't avoid age. It plays a part, anything else would be dumb.
To be honest, I judge someone from what they write. If an arguments good, it says a lot more about someone shouting out about "haha, why should we listen to him, he's only 15" than the 15yo lad who just made a valid point.
Just my 2 cents.
