Regardless of demand, one thing that helps is when someone experienced with old bikes acts as a guide for newer people in the hobby. New people can certainly search the internet, but there is still no substitute for having someone to approach with specific questions or advice (what to buy vs. avoid, common problems, etc.). I think that as experienced old bike people, we have a responsibility to help people entering the hobby to learn about what is out there, how to avoid getting burned, common issues, etc. The hobby is about riding old bikes, but it's also about the other people involved.
