I have been in the scene for years and I still know very little about EVERY aspect of this technology.
those who know more are always like this. in other words you are knowledgeable enough to know your knowledge is nothing but a drop of the ocean.
and regarding these newbies based on what i have seen i think it is mostly because of merit system. many of the topics that are created with a technical subject are for gaining merit. some of them even ask you to give them merit if you liked what you read!
Let's be FAIR, Not all Newbie are dangerous, we can treat this as learning experience from this forum, we can either be critical on the newbie's or be more informative and educational, We are all learning from all of the information coming in about Bitcoin. the news on social media and the issues confronting Bitcoin, the good news we are still here.
