I'm just saying... if well-executed, there's so many possibilities. To the point that an NS app would be the ultimate social networking app -- like a combination Facebook-YouTube-Flickr-etc. app. Imagine the possibilities:
Videos: Watch, Upload, Comment, Rate, etc. plus you could do something cool like shake to show a random video/edit.
Photos: View, Upload, Comment, Rate, etc. plus you could do the same thing -- shake to show a random photo.
News: Read, Comment, Rate, etc.
Forums: View, Start New, Replies w/ Quotes, etc.
Users: Send PMs, Give Karma, View Profiles, Friend Request, etc.
Hell, you could integrate Facebook Connect so that when you request a friend, start a thread, etc. it would show up on your Facebook Profile.
