What is the motivation? Is it to Glean information or more than that?
It is nice to be among people, some of them vastly different, and discuss topics of common interest. Especially nice that most have backgrounds very different from mine.
Some posts are generated by real issues like the N reg, the IMCR but what drives us to post even on trivia like a guy being told to go around at 450 feet.
That is far from trivial to me - if ever I come to fly at a UK aerodrome I'll know at least about some of the things I should be prepared for. The N-reg issue is far more trivial to me.
Who is the highest poster ever on PPRuNe?
Who cares? Quality has more value than quantity.
Where do we hardworking people get the time to post so much and where from?
I never claimed to be hardworking, and I do occasionally post from the office, but mostly from home, just before or just after dinner.
How much posting is to say how clever we are and better than you? Pecking order? and who are the forum celebs? is that what its about?
Several of my postings have rather shown my stupidity, I think. Nothing wrong with that: I am a foreigner, so there will inevitably be differences, and on top of that I am a beginner pilot with lots to learn everywhere.
I know there are people here whos knowlege shines through and who I learn from!
Second that, except for the typo's.
