What I meant by that is I could have many of the same conversations w/my "goth" friends that I could w/my "geek" friends (long winded discussions about computers or Star Wars vs. Star Trek w/enough Monty Python and Simpsons' qoutes going around to choke a horse, etc.). But the goths tend to be a bit darker, and drink more.

Same tree different branch, IMO.
Stratum9 gave us the defintion of Gothic architecture, literature, and a sampling of what is stereotypically "goth" music, but for a definition of what the goth sub-culture BennyD gives the better answer (if you can call it an answer).
Unlike like the punk or rave sub-cultures there isn't a single thing that "binds" all goths together (i.e. listening to punk and going to raves are needed to called a punk or raver, respectively, but there's no such "criteria" for being goth).
