Even more important than what books you should read, install this bookmarklet asap -
http://kindlebility.com/That allows you to just send articles to your kindle with one click. I think, if I am not mistaken, the author is actually a member of HN, just don't remember his handle.
But this is an awesome service that I love.
I started off with Instapaper, but after a while it started acting weird and getting support from Marco was a major pain in the ass, so I switched to that. Been happy ever since.
If you are a voracious consumer of news and such, there are long-form articles that are perfect to send to your kindle. Check out: http://longform.org/ and there is another one somewhere just can't remember it right now.
Be careful with this bookmarklet though, you can get carried away.
I believe I have a backlog of about 15 pages of articles that I am yet to read and there is no end in sight for me to stop sending them :|
