Do weblogs like Discordia aim to replace mailing lists altogether?
Mailing lists have become such a standard instrument in every area of life, it is not likely that they would be easy to replace. They have limitations, though. Some of the problems mailing lists encounter include domination by a few members with more time than fresh ideas, spamming (flooding the list with petitions, forwarded messages, etc.), trolling (disruptive behavior). Discussions may be choked by a plethora of announcements or excessive self-promotion. It is often difficult to find the right balance between moderation and openness. Based on past experience, Discordia is designed to avoid or alleviate problems like these. This will not make mailing lists obsolete, but should open up the territory for more diverse communication.
