> Why not a series of blog posts?

It seems pretty self-evident that they wish to exchange something of value for something else of value. This is a pretty common activity among humans.

Unfortunately, as we see here, "instead, why don't you do even more work to change it to my specifications and then give it to me for free" is a common counteroffer.

I am already writing every tip as a blog post. But those blog posts take a full day to write as they are much more detailled compared to the short summary in the ebook. My time is limited like yours, and the short ebook is the best way to spread the knowledge: You get the information now, and I'll notify you when those full articles are written.

Hey man, thanks for the book.

Don't forget you don't owe these guys what they're asking for. You've done the work to share your knowledge, they can do the work to gather it.

Take a shot every time a HN pedant types "Why don't you just X".

You, the reader, don't have a choice between a series of blog posts and an emailed pdf.
