How Tor Works: Part One
In part2/3 or wherever you discuss hidden services, can you please not call them the "dark web"?  That term is being thrown around so much lately that it has lost all useful meaning.Imho the "dark web" means those parts of the web not publicly visible, ie not indexed by search engines and/or places not accessible to the public.  Most hidden services are indexed and are publicly accessible ... so they are not by definition dark.
