A new way to read the Sequences:
https://www.readthesequences.com
It's also more mobile-friendly than a PDF/mobi/epub.
(The content is from the book — Rationality: From AI to Zombies. Books I through IV are up already; Books V and VI aren't up yet, but soon will be.)
Edit: Book V is now up.
Edit 2: Book VI is now up.
Edit 3: A zipped archive of the site (for offline viewing) is now available for download.
Sorry to nitpick but you haven't said in which way it is better than the on-site Sequences or the PDF.
See my reply to DragonGod below re: comparison to PDF. I think this is easier to navigate, and certainly more readable, than the Sequences here, but of course YMMV :)
