As the author, I've been amazed over the years at how well this resonates with people 25+ years after the fact. I continue to get 2-3 emails a week from people about how it affected them (unfortunately, about half of the emails also ask me to break into something for them).
It is difficult for anyone who didn't live through the BBS years to understand the feeling of no longer being isolated and alone. I strongly recommend Jason Scott's documentary 'BBS' (in which I'm interviewed) for a glimpse at a bygone era.
