A lot of readers sent me this New York Times story last week: My Son, the Blogger: An M.D. Trades Medicine for Apple Rumors. It's a profile on blogger Arnold Kim, who runs the Apple-centric gossip/news site MacRumors.com. The blog started as a hobby eight years ago, but became so lucrative and successful—it now attracts more than 4.4 million visitors a month—he quit his day job practicing medicine and started blogging full time. How freaking cool is that? Sorry, Mom and Dad. I'm quitting the doctor thing to be a blogger! I love it.
