Don't you think it's a cool way to learn and earn at the same time?
That's great actually! Sharing your knowledge and earning at the same time, I agree with your statement that sometimes you'll learn a lot and have a better understanding on getting a position in trading, sometimes it's not bad to hear other people's insight as you might give you more information and might expand your perspective regarding the market but sometimes you'll encounter useless information and insight but no matter what, you'll still get more ideas in the community that's why there's also a good way to share your strategy and insight and also let them criticize (constructive criticism) your idea.
Perhaps, listening and hearing insights from experienced traders helps us improve and gain more ideas in return but it doesn't mean that we could be like them. I said NO and why? Because we all have different opinions in making a decision and an evaluation in a particular situation making you and me have different results. This is the fact that we can't change which is why not all traders become successful even though we follow the same person and the same strategies still, it results differently.
Of course, there is a big changes as we learn more and bigger chances to earn more but yes, it generally depends on a trader and how they manage themselves, especially in dealing with their emotions.
