Similar. I put out free technical blogs and charge for technical books. For a demographic that's allergic to paying, engineers are really profitable.

An extra $30k/year is pretty nice for a sidehustle I think. Mostly on track to do double that this year.

And of course, if a company asks for consulting, I charge. But I'm not focusing on consulting these days.

However a company is paying me to develop tech material for them as a content marketing strategy. At $600/article it's not a bad gig and I'm probably undercharging.

So .. uh .. the answer to your question is Yes, sortof.
