"Explaining Benford's Law" may have been a more accurate title, but "Why 30.1% of numbers start with 1" brought this neat article to a larger audience. Taken too far, though, that kind of thing can ruin social news sites. Headlines have always been a gray area.
Unfortunately, "Explaining Benford's Law", which is the actual title of the article, is a complete misnomer, as the article doesn't actually explain the first thing about Benford's law. It just restates Benford's law and gives examples. There is no explanation or derivation at all.
