1) This is their world, college, even if it's talked about on HN they should not be conforming to our standards. Education, like software development, is about experimenting and failing and learning from it all. College is the place where they can do that. Step back and give them room to grow up.
2) They would be poor students if they weren't doing things that challenge everyone else, especially the older generation. This is where innovation and innovators will come from. I hope they don't give %!#@! what everyone is saying about them; it would be tragic if we quashed their spirit.
