I'd assumed it was an artifact of the storage mechanism that pg didn't consider problematic enough to fix. PostgreSQL, for example, has no order guarantees unless you explicitly call for them, but seems to order by last update to the row. Not that I'm suggesting that a SQL database backs news.yc; pg seems to have a preference for filesystems over databases.
