I actually like alternative solutions listed when something is posted on HN that I know nothing about. It's obviously best when the poster does some homework and lists the largest differentiators. I've seen the question "how is this different to X?" used, more often than not, in more of a combative context however where the user defends an alternative and then points negatively at the original. Just my $0.02 and I"m sure there's a better format that could be used, just not sure what that is exactly :)
