I think the purpose of each mailing list should be determined by that list's owner(s) with input from whatever sources the owners care to take into consideration. So, the question "Are anonymous postings appropriate?" is only answerable (in my mind at least) in the context of a specific list. Each list owner has to answer that question for themself and their own list. In other words, I don't think there's much utility in trying to decide the point for anyone else. Both Geert Marien and Paul Graham are free to make their own decisions on the matter, and don't need to consider anyone else's opinions in doing so. For those who would like to prevent anonymous postings, please note that it's virtually impossible to do so. My guess is that if it's really that important to only have postings on the list from known sources, you're best it so create a controlled subscription list where only the list members can submit messages. And even so, it's no guarantee that people won't spoof you despite those roadblocks. -jj
