I enjoy reading Ken's blog. Why? Because at least he has an opinion, unlike many camera testing sites and magazines. In fact, I can honestly say I've learned a lot from his site.
And, no, he's not a dummy. His writing style is entertaining. Keep in mind that most of his readers are not camera nuts like us. I've sent quite a few friends to his site who happily told me later that they were entertained and informed enough to make a $5 donation.
If I recall correctly, Ken says that he used to make $170K a year before he started his site "for fun". His site gets over 100,000 hits a day. Let's say that 1 out of a 1,000 (.1%) send him $5, which apparently is the average donation on the Internet. That's $500 a day, or $182,500 a year, or more than he used to make as a sales engineer. In fact, I seem to recall reading somewhere that he hinted that he is making more money now than he used to in his career.
So, lets see... photography fan quits his job, starts a camera blog, makes more than he used to with a job, has his own business where he works his own hours, his own deadlines, gets to play with his kids while most guys are at work, plays with camera equipment all day, and gets to deduct his camera equipment and trips as business expenses.
Ken Rockwell a dummy? Nope. My hats off to him.
