I've had similar concerns and I agree with a lot of this.
Get this closer to a 7th grade reading level. This sets a low bar at potential readers who can understand 'blockbuster' books in English. (This might be accomplished purely with the terminology concern/change above)
If we really want to approach a 7th grade reading level, then we had better aim for kindergartners. I remember reading through the book trying to imagine how to bring it down several levels and thinking about just how many words I was taking for granted as a high-IQ adult who has had plenty of time to just passively soak up vocabulary and overviews of highly complex fields. I just don't think we're there yet; I think that's why there are things like SPARC where we're trying it out on highly intelligent high school students who are unusually well-educated for their age.
Change all hyperlinks to footnotes.
To my knowledge this is already a priority.
Is there any ongoing attempt or desire to do a group edit of this into an 'Accessible Rationality'?
I find that there's a wide disparity between LW users in intelligence and education, and I don't know if I see a wiki-like approach converging on anything particularly useful. I would imagine arguments about what's not simple enough and what's not complex enough, and about people using examples from their pet fields that others don't understand. It might work if you threw enough bodies at it, like Wikipedia, but we don't have that many bodies. I don't know how others feel.
See Mark's post regarding 7th grade; my intention was aimed at adults, who (for whatever reason) seem to like the 7th grade reading level.
I'm not sure how to effectively crowd source this without getting volunteers for specific (non-overlapping) tasks and sections. I share your concern with the wiki-method, unless each section has a lead. At work we regularly get 20 people to collaborate on ~100 page proposals, but the same incentives aren't available in this case. Copyediting is time consuming and unexciting; does anyone know of similar crowd sourced efforts? I found a few but most still had paid writers.
Eliezer Yudkowsky's original Sequences have been edited, reordered, and converted into an ebook!
Rationality: From AI to Zombies is now available in PDF, EPUB, and MOBI versions on intelligence.org (link). You can choose your own price to pay for it (minimum $0.00), or buy it for $4.99 from Amazon (link). The contents are:
The ebook's release has been timed to coincide with the end of Eliezer's other well-known introduction to rationality, Harry Potter and the Methods of Rationality. The two share many similar themes, and although Rationality: From AI to Zombies is (mostly) nonfiction, it is decidedly unconventional nonfiction, freely drifting in style from cryptic allegory to personal vignette to impassioned manifesto.
The 333 posts have been reorganized into twenty-six sequences, lettered A through Z. In order, these are titled:
Several sequences and posts have been renamed, so you'll need to consult the ebook's table of contents to spot all the correspondences. Four of these sequences (marked in bold) are almost completely new. They were written at the same time as Eliezer's other Overcoming Bias posts, but were never ordered or grouped together. Some of the others (A, C, L, S, V, Y, Z) have been substantially expanded, shrunk, or rearranged, but are still based largely on old content from the Sequences.
One of the most common complaints about the old Sequences was that there was no canonical default order, especially for people who didn't want to read the entire blog archive chronologically. Despite being called "sequences," their structure looked more like a complicated, looping web than like a line. With Rationality: From AI to Zombies, it will still be possible to hop back and forth between different parts of the book, but this will no longer be required for basic comprehension. The contents have been reviewed for consistency and in-context continuity, so that they can genuinely be read in sequence. You can simply read the book as a book.
I have also created a community-edited Glossary for Rationality: From AI to Zombies. You're invited to improve on the definitions and explanations there, and add new ones if you think of any while reading. When we release print versions of the ebook (as a six-volume set), a future version of the Glossary will probably be included.
