Usenet, in my experience, is reachable through a variety of easy-to-use web-based providers. Easynews, etc... I agree that it's ill-suited in the sense that often the files are split into parts and often need re-assembing or other such work. But it's fairly trivial stuff that a user may already be familiar with. Other than that it's super easy. Torrents, at least in my experience are not so straightforward due to the required installation of a client. I think users are hesitant to install it on their machines. Just my take based on limited experience.
