It's a Special Interest forum. The Smoker's Lounge serves its purpose by providing and sharing information with a niche audience. As others have stated, other Special Interest fora (Disability and Women's Travel) in which I do participate (I don't participate in the Smoker's Lounge, as I don't smoke) may not have as much traffic as posts in hotel and airline fora, but they provide valuable information for specific types of travelers that is not easily accessible (or available at all) elsewhere on FT.
