I'm actively working on reading and checking the math in a 300 page textbook in order to make a post on LW six months from now that maybe 100 people will read and almost no one will take seriously.

Thanks! But 100 people is a serious underestimate: far more people read your previous posts on the subject (only a fraction of readers vote, and you got 43 upvotes on your post about nanotechnology). If you wind up with some substantive technical criticisms, I expect Eric Drexler will take time to reply, I for one will be seriously interested, and it will be frequently linked to in discussions about Drexlerian nanotechnology.

The most-viewed LW post has hundreds of thousands of hits, and there are many at 10,000+ (search the link for "pageviews").
