Yes, John Siracusa now known mostly as a co-host for Accidental Tech Podcast said that if he actually calculated all of the time he spent writing his 100+ page reviews of MacOS for Engadget from 10 to 10.10, he earned less than minimum wage. He did it more as a hobby.

I had a part time working hobby as a fitness instructor for over a decade that definitely wasn't worth the money once you took into account the prep work, travel, etc.

Edit Correction: Ars Technica not Engadget
