Netnews has subscriptions. On the client side you can say which newsgroups you want to read, and on the server side you can say which users are allowed to read which groups. >Really, the participation and scaling characteristic differences between >bulletin boards -- which are essentially broadcast -- versus mailing >lists -- which are multicast, are huge. Huh? Usenet is multicast, with each server sending messages to other servers it knows. I suppose it's broadcast in the sense that everything goes everywhere with no overall control. That led to vast amounts of spam. Even worse, as spammers started scraping addresses off usenet messages (which as far as I can tell they no longer do, but it's too late now) people used fake addresses, leading to no accountability. One of the reasons mailing lists are useful is that there are list managers who can control who gets to post to the list and eject trolls. Moderated newsgroups sort of do that, although they have other issues.
