Nephrologist quits medicine, blogs full time

The story of MacRumor’s Arnold Kim: “How successful does a blog have to be to get a physician to quit? Let’s do some math. Silicon Alley Insider quotes Quantcast numbers reporting a “staggering 37 million page views a month”. This makes MacRumors, #571th biggest site on the whole Internet. If we assume quite modest monetization at $1 CPM (cost per thousand pageviews), he would be making about $37K a month. If he monetizes at $10 CPM that would be $370K a month.”
