1. How possible is an, approximately, 80% of all forums' members to have a long term winning strategy such as yours?
Highly unlikely.
2.Would not that be highly unlikely?
Of course.
Now this question is not entirely hypothetical but based on my personal observation over the course of years;
3. There are not as many members as they used to be.
Apparently.
4. From the fewer members there is significant less interest in participating on topics regarding strategies and in general about how to win on long term basis than what it used to be on the past.
This is my conclusion.
5. People prefer to discuss more about unrelated subjects rather than contributing all as a team to a mutual and beneficial cause/goal.
Unfortunately.
6. More minds are able to achieve easier and better than a single alone.
Not necessarily.
7. Even if you would share a long term winning method, do you think that all gamblers worldwide would read your topic?
No.
8. Do you think that from those who would read it all of them would use it, let alone to the letter??
No.
9. Do you think that casinos would close, stop roulette game, or even change its rules, which have never changed since 1 and a half century ago???
No.
10. What is the real reason behind this behavior?
I believe that it has to do with the ego like many other issues.
11. Don't you think that forums are a great mean to connect people worldwide under a common cause/goal?
That would have been the ideal, but people don't operate optimally in general.
12. Why they are not focused groups of individuals, instead we see too much blah blah speaking about nothing practically, or about promoting products and services to potential customers?
There are two main reasons, or the lack thereof, motivation and organization.
13. Why when there were important efforts a few persons derailed those topics and from the practical considerations we ended up striving to prove a point, defending our positions from the intruding negativity?
Human nature I guess, easily carried away of "path", covers too much on the "surface" but not in depth before he/she eventually realizes that life has passed.
14. If some have found something which works AND don't desire to share it then what on earth are they doing here?
Bragging and laughing with others for satisfying their ego.
15. If they want to have a conversation and/or pass time then why they don't do it outside forums, with any other persons and/or activities??
Who says they don't, someone who could gain money almost by demand most likely have plenty of time as well.
Thank all of you for your sincere replies!
