Sure! Though I don't actually have much in the way of commercial performance details - it's all split between many quarters of receipts over the last few years, that I'm too lazy to aggregate...
I'd guess that I didn't profit more than a couple of thousand (British) pounds (of both paper and digital sales), after all the publishing costs had been paid for. I think there's still quite a bit of paper stock; I'm still waiting to find out how much is left (though I'm unlikely to try to sell it - I'll probably give them away at conferences, etc).
The parent company that owned the publishing company was acquired by Monotype, and they made the difficult decision to close down the publishing arm as part of the acquisition. The contracts with all the authors were nullified, and all rights returned. As the book was a few years old, and some of it out of date, I figured the best thing to do with it - especially as I'm 100% focused on my startup, and it was never going to make me rich - was to "give it away" to see if it could have any extra life.
It's about 80,000 words and I wrote it over the course of a full year (of traveling; I was also doing some consultancy, so it wasn't full time). So I'd rather that effort was 'available' for other people to possibly use.
You might as well put a "buy the dead tree version" link on the site - it's a potentially useful resource for start ups to buy and put on the shelf, and it might make you a few extra quid?
I'm 100% on http://bipsync.com (as I have been for the last year or two), a startup initially targeted at Hedge Fund analysts and other professional investors. We were lucky enough to raise a seven figure seed round, so have had the time to go through quite a lengthy customer development phase with some reference customers to really nail the product-market fit. We'll have a public beta out later this year.
You may adapt it for any purpose, including commercially. The only terms are that you need to credit the original source (the website will do) and indicate if any changes were made. There are no other restrictions. Have at it!
Surprisingly, at least to me, I think the chapters on marketing are some of the more interesting ones for the HN audience, and have aged pretty well.
It's quite a high level book, so doesn't go into anything in TOO much detail, but instead is supposed to give an entrepreneur - even non-technical - a good understanding of most aspects of building a web app (or at least, what that consisted of a few years ago).
The dev chapters probably won't hold much interest to HN visitors (as they'll know much of the advice), but the marketing ones, maybe some of the design ones, might have some new insights if you've been focusing mostly on tech in your day to day work.
Given the breadth of information covered, I think you did a remarkable job on providing one of the better, succinct and balanced introductions on the Search Engine Optimization chapter (#23). If I could make one suggestion - your alternate text attribute markup for the images is non-descriptive at best.
And thanks!
