Comments which are voted down are often misunderstood. More often then not, those comments consist just of a single sentence. A few days ago I made a comment, which had 3 downvotes, however the 3 posts where I explained myself had 15 upvotes in total. I think it's great that HN has this feedback mechanism that sometimes lacks in real life (especially in non face-to-face conversations).

How is your first comment relevant? Answer that, and you'll figure out why you were down voted.

Well, I'm sure it's something that could be worked out, but there will likely be naming issues between French and Non-French nuclear engineers working together. It seems relevant to me, given that the topic was to bring French engineers into a U.S. startup.
