I used to be quite heavily involved in flight sim sites! There it was even harder to know who was really on the other end typing away.
We had one person who posted as an experienced 747 Captain. He posted with authority and posters would place questions with admiration at the responses that flowed from this highly experienced Captain.
Then there were a succession of basic flaws which got some more regular posters exchanging private messages about this guy.
He turned out to be a 12 year old kid who got his kicks out of living the dream and taking everyone for a ride.
He felt important and was an absolute master at googling copying answers and adjusting that text as if it was written by him.
Here its not so bad as some of us know each other real world and as stated you get to know who to listen too.
i will also add that we all bring different expertise, some with engineering backgrounds, some with instructing backgrounds, some with law backgrounds, some as experienced PPLs, some as commercial pilots etc etc etc.
Often there will be arguments especially over hurt egos where someone is shown to be wrong.
Sometimes neither are wrong but they hold rigid to the way they do things and that is the way it should be done.
Sometimes the subject matter has been done to death many times and you can almost sense the minds of others scraping the barrel to post a new subject or its a variation on a theme.
I personally do not mind threads going off topic so while the question maybe on landing an aircraft it evolves to taking off because in that broad spectrum of discussion there are always hidden gems.
As stated treat any individual answer with caution as even the best here get it wrong or only see one picture when infact there are a number of equally correct pictures to choose from.
I know with my own posting style that I post to generate discussion and i hope in a colourful and challenging way
but equally know there are those here with much more detailed knowledge than i have or who are much more specialised in certain fields of aviation.
So we all have a contribution to make in our often very different styles and experience levels! We all have a lot to learn from the student to us supposedly more experienced ego orientated pilots
