Pretty trite. I think everybody understands that NDAs are uncool with the cool.

And it's true that the NDA can look pretty stupid when you're some random hacker guy who hasn't done anything and you seem to be taking yourself incredibly seriously with these contracts and agreements of secrecy.

But so what? If you think you're idea is good enough for an NDA, then ask for one. If you're wrong, you'll find out soon enough. But if you're right... the NDA just might work out for you.
