I really don't like the advice for #7 (bloggers do not own user generated content). Not necessarily that he's making it, it's just not the way it should be.<p>If I posted an essay in this comment, it should be up to me to save a copy of the work. Ycombinator should not have to make me agree to give up rights, the relevant rights should be given up automatically by the fact that I donated a copy of the work to store on their servers.
