That's revenue, so not .. quite what he's taking home. Less cost of servers, then benefits which he's not getting from an employer, 401k matching, etc.
Oh I’m not disputing it’s good for a single developer along with the freedom.
It’s just that these projects always get talked up as huge successful life changing products (like Bingo Card Creator and appointment reminders etc) and then have really small revenue numbers attached to them.
Don’t get me wrong, kudos to the developers for building something people love and that give them the lifestyle they want.
I just think these projects are often overhyped to seem more than what they actually are: lifestyle projects.
Frankly, if you don't have a bespoke Pagani Zonda with your initials in the model name, we're collectively unsure that your lifestyle has enough style or enough life. Thinking it over, I might not even invite you to my birthday party.
It's a lot for a single developer. But not a lot for a product that has a lot of mind share and receives a lot of free publicity via outlets like this.
It adds up but yes .. the freedom is nice :)
