The mobile information superhighway is in need of some serious maintenance. That's the take-away from a new Yankee Group evaluation of 32 consumer-facing mobile Web sites. The market research firm scored the sites on a scale of one to 100, grading them on 25 criteria including effectiveness, design and ease of use.

The top score was an unimpressive 67. The average score? Just 54.

Carl Howe, director of Yankee Group's Anywhere Consumer research group said, "If we think of mobile Web sites the way we look at an average seventh-grade class, everyone so far, unfortunately, is failing."
