I have written a short essay entitled "Escape Form Plato's Cave". It is
about the fact that most of amateur astronomy has been stuck in a two
dimensional viewpoint. I would be most interested in hearing other people's
thoughts on the subject.
Yes, the link is to a page on my commercial site. However, I think the essay
stands on its own. You might think of it as my doing market research ;-)
