For my part, I'm always sad when a meta comment that has nothing to do with the content of the post ends up getting voted overwhelmingly to the top. It's less your fault than that of the overwhelming upvoters. But it's an unfortunate glitch that reliably mars HN discussions, and I don't know of a good answer to it.
By the way, the reason we reverted the title in the first place is that the editorialized subtitle immediately provoked a bikeshed debate about the "communities" and whether they're really distinct or not—when the meat of the post is about things like fault tolerance in distributed computing.
