Bitcointalk has been active for over a decade and is still getting better everyday ,Though it has some hard times like the time it was hacked and others but still yet it continues to improve. Bitcointalk has been able to stay this long and improving because of contributions from members of the Forum starting with the founder Satoshi Nakamoto and other awesome members.
It is a fact that Most Newbies now join Bitcointalk just to make money and this is not the main aim of this forum but thankfully you can't really earn without contributing or by breaking the rules and regulations because there are still True members watching this Forum
So my advice for we Newbies is start thinking of a way of improving this forum first before earning.
If I could understand, are you trying to say because the forum "Bitcointalk" has been in existence for over a decades is what makes it the best forum? Or
Bitcointalk is the best because it was able to get contributions from it's founder "Satoshi" and other members? Because there are more other vital issues which I thought you would have said which you didn't. Because I thought maybe you would have said Bitcointalk is the best forum so far because it teaches us all we need to know about Bitcoin and it's ecosystem, or Bitcointalk is the best forum so far because it does not restrict any nation on the world, but it is worldwide and user friendly, e.t.c
