Usenet was the original threaded area found back when the internet was young and most people used unix or other non-graphical terminals to access them. There are thousands of "boards" or threads, covering every type of subject you might be interested in.
Later on, people created bulletin boards and usenet kind of died off a bit (excluding the adult-oriented types) but it's still around. I download books for my old Treo phone off of there and recompile the books - sometimes a book can comprise 10 or more files.
I know there used to be some cigar threads there, but I never went on them.
CA is actually a Bulletin Board, but blocking software can be programmed to disallow access to certain subjects like tobacco or smoking.
Hope that helps a little....
