There is always a good action in every step they do. Just like in making the project popular, there are many ways to do, one is promoting through media but I think it is quite expensive to do that thing. Better the team find other ways which can have a double strategy that both side will benefit.
Promoting can help in making the project known or shall we say popular. That is why it is important to have an informative and understandable platform so that people will not find it complicated. They can totally decide directly what the project all about and how useful it is.
