One difference to mailing lists of more recent times, besides technological differences, is that there was more of a sense of shared culture across groups. Groups certainly differed (some topics might have even had parallel groups in regular and in alt.* hierarchies?), but not even remotely as much as mailing lists differ. Certainly more free for all babble (because it was) than the more moderated or even announcement-only end of the mailing list spectrum that is enabled by their centralised nature.
Usenet is typically accessed with a news reader application like Thunderbird. Thunderbird is not just a email client. It is also a news client that allows you to subscribe to and post to newsgroups.
