I understand that bitcointalk is the largest forum on the web, but you need to understand that you will not learn about many projects if your source of information is only this forum.
Although top projects as I understand it do not need this already. By the way, it seems to me that many projects do not try to publish a topic about their project, since the forum has a very strong community and then FUD will start in their direction. But in turn, many different one-day projects appear here.
Good projects are listed outside the forum but if you are a bounty hunter the only thing that you could get here are those projects to which you think would be better. In my case I only wait to join new projects like the project I had right now. After seeing it in the altcoin bounties section I decided to join right away because I have not always seen a legendary rank user promoting a project. This because account here is very precious and that they do like to make a thorough research as a bounty manager before accepting the project.
