>Putting it in perspective, $200,000 over five years averages $40,000 per year. It's definitely something, but that revenue would not be enough to replace my salary, nor do I think my other book projects will match its success (though I'd love to be surprised!).
That depends on where you live I suppose. $40K per year will likely put you in top 1% richest in my country. My case is an extreme corner case, but my yearly expense is around $1500-$1800 (which looks likely to be earned with my ebooks this year).
>You can buy Ansible for DevOps, 2nd Edition on Amazon, LeanPub, or iBooks.
Any reason you aren't using https://gumroad.com/ as well? That is much better than leanpub with fees being
* 5% + charge fee (3.5% + 30¢)
* or, 3.5% + 30¢ per charge only with different tiers (https://gumroad.com/settings/tiers)
And payment withheld is maximum 2 weeks instead of possible 75 days with leanpub
