Thank you. I find this valuable.
However, I personally find the cover distasteful, even though it is obviously meant to be in jest.
I think it is better to avoid any hint of the trappings of religion or Eliezer as the great prophet.
I have personally encountered people who are sympathetic to Eliezer's ideas but are wary because of the pattern-matching going on that makes them think "potentially dangerous cult leader". The cover doesn't help that problem; in fact, it perpetuates it--whatever the content of the document.
As we know from presidential politics, impressions matter, even or maybe especially when they are superficial.
Update 2015-03-21: I would now strongly recommend reading Rationality: From AI to Zombies over this. Though the blog posts I collected here are the starting point for that book, considerable work has gone into selecting and arranging the essays as well as adding thoughtful new material and useful material not in this collection. Only if you've already read that should you consider starting on this; you can always skip the essays you've already read.
This is all Eliezer's posts to Less Wrong up to the end of 2010 as an EPub. Can be read with Aldiko and other eBook readers, though you might have to jump through some hoops on the Kindle (haven't tried it). I shared it privately with a few friends in the past, but I thought it might be more generally useful. Highlights include that all the screwed-up Unicode is fixed AFAIK.
Source code.
Update: have now made a MOBI for the Kindle too.
