Here's my list of submissions: https://news.ycombinator.com/submitted?id=ben_w

Of those ten:

• 6 had zero comments, 1 had only my own comment • 1 had 7 • 1 had 17 • 1 had 148

I have no reason to think there's a nationality thing here, stuff just falls off the top fast and most people don't comment or upvote… same as with most comments themselves.
