Heh, I'm usually on the ideas "side", but since I've publicly shot down the data centers in space idea, the shoe is on the other foot.

I'll just say that if there are some obvious enormous drawbacks to an idea, then you are responsible for mentioning your counter to them when presenting an idea. "Do X by seemingly breaking the laws of physics" had better be accompanied with at least some mention of how you are not, in fact, breaking the laws of physics.

There are two sides, the one presenting an idea and the one receiving it, and both have responsibilities. The article is about one way that one side often fails to maintain one of its responsibilities. No more than that.
