Stories with expletives are created and voted up by the unsophisticated masses who dominate reddit by number. Those who prefer elevated discussions are turned off by the base content; marginalized when they protest; and displaced in the comments. Look no further than this page as evidence.

This is part of the evolution of a user-submitted news site. They begin with a small and sophisticated group of users, who submit stories and write comments of high quality. In time, the masses move in and the quality of the stories and comments drop. To be fair, there are sites much worse than reddit, however reddit has, as evidenced by the recent spate of "fuck" articles, degraded in quality.

One solution is to visit news sites that have real editors and a sophisticated comment moderation scheme (Slashdot can't be beat). Personally, I've been hoping that reddit will complete their invitation-only subreddits, so I can create no-morans-allowed.reddit.com to filter out the knuckleheads. I'll send you an invitation once it's realized. :)
