A little vocabulary lesson may be in order for the editors on the Yahoo! front page. They seem to think that infamous is a synonym for famous. It isn’t.
The American Heritage Dictionary says that infamous means “Having an exceedingly bad reputation; notorious; causing or deserving infamy; heinous.”
The dress in question was revealing, but not wicked, abominable, degenerate, or any other synonym for infamous. It is, however, famous.
Yahoo! writers use infamous a lot, when they mean famous. But sometimes they really, really screw up and come up with something that could live in infamy.
