“Take on Apple. Writing something bad about Steve Jobs
or a new Apple product is the sure-fire way to get the zealots in a state of fury.
Two days later and I’ve got 2000+individual people visiting that post about the iPod photo,
over 52 comments and lots of emails. This is to be expected of course, but of the two or three
times that I’ve done it and gotten such a response, it still surprises me.”
