I agree with the first post. Some people can really be rude. Some more than others, but there are a few individual I have not heard a single bad word out of, like Layne Pemberton, Qquake, Grouch, and quite a few others.
This is my observation, but a lot of the heat goes to us youngins. Someone prove me wrong?
I often get impatient when people ask things I think are obvious. I have made a few impertinent posts in my time here (three I can remember). Luckily, despite my relative youngin'ness" and my 5-post-a-day record, I have never been on the receiving end of any of this criticism.
In my opinion, if you were to determine who got the heat" it would be mostly those who at least somewhat deserve it for not doing their research before asking questions, a category which seems to coincide with youth. This includes the people planning moon shots, liquid nitrogen/hot water liquid engines, and quite frankly, two stage level 2 rockets planned before having even seen an AP motor. However, one can earn respect through showing good work and making helpful comments, a perfect example of which can be found in what aksrockets does on the forums.
I do have to give some respect to blackbrandt for taking the heat and learning from it, as we all hoped he would on our own sides of our computers. However, the ends do not justify the means, and adult sarcasm is surprisingly often lost on the kids, so we should all take pains to imagine ourselves receiving the messages we write before posting then.
If we can all do that then I imagine the forum would become a much nicer place even for wayward, misguided souls.
As a side note: one situation in which I personally discriminate by age a little is typos. I understand people less accustomed to computers making mistakes, but anyone in my generation or later ought to have the capability to type without frequent errors, and my opinions of them are often influenced by such.
