He has a blog post on the site about the approach he took.

Instead of going to Penguin to get his book published, he decided to try doing the whole process himself. That included getting translations done, coordinating printing, building a webstore, etc.

It's pretty cool tbh

This is very true, in his about me page, he says that he does not rely on any type of cloud and hosts through his own servers. A very unique approach indeed.

Based on https://sive.rs/m and https://sive.rs/n he's self-publishing electronically for $15 (or $4 more for paperback), so I guess the costs are quite small.

My guess is that he's trying to see if he can do bookbaby.com

edit: wow that actually exists haha

> I made 5000 limited edition hardcover copies of each, but those have sold out now.

Is this not part of the 250?

I guess, so maybe it's >250K profit?

Sounds like Derek Sivers did. Wouldn't be his first time giving to charity.
