As also mentioned by OP, blogging for your book while writing it, is a very important exercise and it's so underrated.

I've spent countless hours during Covid isolation looking for good to excellent books on Engineering and Computer Science. Excellent book authors for examples Lewis Van Winkle, Pieter Hintjens and Andrew "bunnie" Huang do have blogs.

p/s: To be honest the three authors examples are from an Amazon's book reviews but I hope you've got my point.
