I agree re. an included workbook and to clarify, when I said "go along with it" I meant "related/parallel content," not "physically attached."
I think a downloadable PDF (easily accessible, easily revised/updated) for little or no cost would be optimal. I'd be willing to pay for it to cover the time and effort invested by other LWers. I'd also volunteer my time for free to the project as an organizer/assembler to assist those willing to supply/decide the actual content. I have a decent amount of experience with writing technical manuals and a fair amount of experience using LaTeX, which would lend itself well to the writing of an organized, footnoted workbook type of publication.
I think that it may be worth moving this article to the main page.
If perhaps two more agree with this, I'll do it... otherwise forcefully suggest it and I'll do it based on your recommendation alone. Again, I really have no idea what constitutes a top-level-worthy post!
Please move this to the main page. I'd love to see it done; I don't know if there's anything I could contribute in the way of time and knowledge.
I also second (third?) the suggestion for trying to make it a companion to The Art of Rationality. Desrtopa, why do you think fewer people would buy it if they came together? Is it because books with workbooks attached look intimidating?
Note: This was originally posted in the discussion area, but motions to move it to the top level were made.

My own desire to improve my rationality coupled with some posts criticizing LessWrong not too long ago led to an idea. For reference, the posts I mean are these:
