Not dead yet
BBSs aren't dead. Their spiritual descendents are forums : owner-moderated, often with a personal agenda, often for self-promotion. Although I can see their good points for certain uses, I'm unable to understand why email groups are pushed into forums because 'they're more modern'. They're not, they're just BBSs with a pretty web face and all the disadvantages - polled for updates, unintegrated with push delivery systems (that have been modern since the 80s), a home for cute features and draconic rule.
