Ralph, you've mentioned one of the biggest advantages of e-mail: it just shows up in your mailbox. Its other advantage is that it's the lowest common denominator of Internet services. It reaches more people than any other avenue. The main problem with mailing lists is that they don't provide any structure. E-mail messages are not organized by topic. If you only subscribe to one or two mailing lists, and the traffic on your lists is fairly light, the lack of structure might not strike you as a problem. But when a mailing list gets a lot of traffic, and especially when it develops several different threads of conversation simultaneously, it gets very difficult to keep track of it all. For this reason it's rare to see more than two or three active threads in a mailing list. On the other hand, on a good conferencing system, a single conference can easily support dozens of active topics. E-mail also puts more of a burden on individual users, who have to sort, file, or delete all the messages. I find this to be a pain even with a good e-mail program like Eudora, which can automate some of the sorting and filing. Mailing lists show another drawback when it comes to supporting fast-paced discussions. There is an inherent time lag in broadcasting e-mail messages, sometimes measured in hours. If someone asks a question, several people might answer it, not realizing that they are duplicating efforts. But in a conferencing system that resides at a central location, everyone reading a topic can be sure they are seeing everything that has been written up to this very moment. In a very active topic, it's still possible for another response to slip in while you're composing your own, but it's much less of a problem because the only delay is the amount of time it takes you to type your response. There, have I slammed e-mail enough? I should note that we seem to be using e-mail fairly effectively for this discussion, so it does have its uses. All my comments apply to mailing lists vs. conferencing in general. Whether the conferencing system is Web-based or not doesn't really matter.
