Thanks for this, Jason. You've always epitomized one of the best things about the startup world -- that those who have achieved some level of success take it as their duty to mentor and assist the next generation of entrepreneurs. After all, none of us would be where we are today without our own great mentors along the way.

Thank you a ton. This industry is where it is because it's about pay it forward. Be fortunate enough to do well, teach those lessons, and pass those connections forward. I had to get everything I wish I knew 5 years ago down on paper.

A very kind offer.

Being in the UK I've taken such offers in the past, but unless you mark every package as a gift and fill in the paperwork for it, HMRC will slap on an import tax and Royal Mail slap on a handling fee.

With that in mind, it's cheaper and less hassle to obtain the free book by paying for it.

I've gone and purchased the Kindle version.

Wouldn't have done so without your offer though, and that is appreciated as are all your comments on here.

I can't believe how awesome you are for doing this. I've been following you on twitter for awhile and consider you a role model for how a new/young CEO should behave. This isn't the first time you've freely shared your knowledge, and it certainly won't be the last, so thank you! Thank you very much indeed!

Sounds great, thank you! Just sent you an email. Hope you're sending to Poland :-)

You can sell your Kindle books without DRM if you're the publisher.

Ah just saw on Amazon you're published by Penguin. Guess this doesn't apply then.

Awesome, you are getting my e-mail right away!

Thanks a lot. I've been looking forward to the book since hearing you speak in Boston at Xconomy. Can't wait to read it.

Awesome! I'm looking forward to reading your book! Thanks for passing your lessons on.

This is an amazingly generous offer. Thank you!

Thanks a lot, that's awesome!

Thank you!
