I like the idea, but I think it has been done before on other blogs. Mr. Money Mustache and Early Retirement Extreme come to mind, which were written by a (now) retired software engineer and a physicist, respectively. Their advice may bear repeating, but I do not think I would purchase a book on the subject. There are so many free resources online; it seems financially unwise to spend more on a book.
But may I ask, who are you, and what are your qualifications to speak on this subject?
As for who I am, google my username, and I'll pop right up. I've got a plausible record of writing non-fiction books enough people want to read to make a decent enough living. I don't claim to be a financial wizard, but I don't think you need to be one either. (I'm about 50% convinced there are no such wizards. Some people do beat the market, but it's not apparent that they do so through enhanced skill or knowledge.)
The basics of personal finance are well established and have been for about 40 years since John Bogle invented the index fund. The main skil...
What follows is a rough outline for a possible rational financial planning sequence that was inspired by some other recent discussion here. I'm not sure how useful this would be to how many people. I know there are some LessWrongers who would enjoy and learn from this; but I don't know if there are 5, 50, or 500. If you'd like to read it, let me know. If 500 people tell me they can't wait for this, I'll probably write it. If 5 people say maybe they'll glance at it, then probably not.

If there are any topics you'd like to see covered that aren't here (wills? lawyers? the financial press?), let me know. Similarly, if you think there's a section that doesn't belong and should be dropped, let me know that too.
One caveat: while some sections are fairly generic, others will be very U.S. centric. The most specific advice will not be applicable to non-U.S. citizens and residents. That does limit the audience, but there's not too much I can do about that. Perhaps if it's successful I can seek out co-authors to do UK, Canadian, or other country editions.
A question for people who are interested in financial planning material: If this were available as a complete book (electronic and paper) today, how likely do you think it is that you would buy this book instead of one of the other available books on the subject? What would you pay for such a book? If this were available as both a book and a sequence on LessWrong, how might that change your decision?
For now, this discussion thread is just a minimum viable product (MVP) to find out if a sequence is worth the time it would take me to complete. If the MVP pans out, I'll write and post one or two of these chapters to further gauge interest. If the MVP doesn't look promising, I'll drop it and move on to my next book idea.
