This book has always been free right? It started life as a free HTML version and they only added the pay-for-PDF later when it became successful.

Kudos for making the whole thing free. But it wasn't that big a leap.

No. Originally it was solely a $19 PDF. They sold 23,000 copies (so $437k+ worth) before rolling out the free Web version in late 2006: http://37signals.com/svn/posts/85-getting-real-the-book-now-...

True, but a lot of people bought the PDF for its benefits over the online version (portability, offline, permanency). I already read it but downloaded it to my dropbox anyways for those reasons.
