You know, I would recommend VidCon, not only for the creators of large-scale projects, because this is a unique opportunity to get to know like-minded people, show your idea, and maybe someone will most likely appreciate it, or maybe someone who owns the same idea like you and do not know how to properly implement it?
Hmm, so share your experiences! Help your neighbor!) This is done not only in order to find support from the outside, but also unequivocally in order to find your audience, fan, like-minded person, colleague, sponsor, and so on.
