Summer Plans: Dance?

<p>Hey everyone! I'm currently a junior in high school and I'm just thinking of summer plans (the day before the AP English Exam (; )
Anyways, so far, I will be interning at a psychology lab at UCLA, learning a foreign language, and learning some skills (chess and golf). I'm also the editor-in-chief and founder of an online cultural magazine.
I've been a dancer for a while, and I was thinking about chereographing my own dance pieces and posting them on youtube. I really enjoy dancing, and it's been my hobby since elementary school. Do you guys think that posting dance videos online are a good idea? (I'm talking about for college admission/application purposes).
My GPA is a little low for the colleges I'm aiming for (3.6-3.7ish). Do you think its possible for me to attach a Youtube channel to applications? Basically... if my ECS become successful, do you think this will compensate for my subpar grades? :/
I'm looking into UPENN, UCLA, NYU, USC, BU and a couple other UCs.
Will being a good dancer increase my chances of being accepted to a college that is recruiting for their dance team? o:</p>

<p>The only school that I know of that allows one to attach a YouTube video to an application is Tufts. Perhaps dance programs proceed differently…</p>
