Ask HN: Has anyone here self-published a book? Any advice?

Hi there,

I am close to finishing my book and keen to get it published. I figured it would be easier to self publish (could be a wrong assertion), and wondered if anyone had any advice? Have you done it before? Anything to avoid? Anything I should definitely do? Any good sites to promote it on?

N.B. The book isn't a technical book. It is a comedy book set out in the style of a blog.

thanks!
