I think the problem with the onelist/egroups maillist was that the BBS had already gained momentum. Whilst it was much more convenient than the BBS you missed out on all the great discussion going on. The new lists have both advantages, more convenient, and you get to listen in on the BBS discussion.

FWIW the maillist does archive the messages to a webpage so newcomers can drop in and browse old messages (Not as pretty as the BBS but much faster to browse)

Anyway, it's obvious there is demand for both. Ideally we'd be using a package like http://www.netwinsite.com/dnews.htm or http://www.teamware.com/ so that discussions can be bidirectional through both interfaces.
