Conspicuous nonconsumption [0], as I call it, is all the rage in SF and among engineers. That's why everyone wears hoodies and tshirts: to show that they're different from MBAs and the suits and the bankers. But that's just another way to show your status: you are the member of an exclusive club that doesn't need suits to have high status.
And so with your blog. You're identifying as part of a group that's too good for status symbols. You're explicitly saying "I'm not like you" and implicitly saying "I'm better than you because I don't need whatever things you find valuable".
You're showing off your non-consumption for high status, in exactly the same way that they're showing off their consumption for high status. At the end of the day, you're both just showing off for high status! [1]
