Now, while I'll certainly be glad to have something to show somebody who wonders just what in the heck a "Brony" is, I can say that, I, personally, don't need validation from anything. Bronycon fascinates me, as do the European Brony conventions the filmmakers will be visiting.
Moreover, I want to support someone who wants to make something that is respectful toward the Brony subculture, and who wants to celebrate the creativity and positivity of it. Almost any media interest in us is negative, and paints us all as emotionally-repressed manbabies. What is wrong with someone making a doc where they look at the good things, which are far and away the primary aspects of the subculture?
I'm pretty interested in what my fellow Bronies are doing at Bronycon and other Brony conventions. This documentary promises to provide a respectful look at what the fandom is up to at these cons. You'll need to forgive me, but I don't understand how this translates into me needing the film to validate my choice to be a Pony fan.
Also, as to the amount of money amassed for the project, the creators have already explained how this is going to be a professional documentary, which can take quite a bit of money. They were willing to do it on shoe-string budget of $60,000, but pony fans everywhere went above and beyond to really finance this thing well. This just means the doc is guaranteed to be awesome.
I have to say, on a side-note, that I love how people so close to the show have decided to embrace our weird little subculture.
