It's full of really bizarre spam, though - and I got the feeling that it isn't technically straightforward to stop people from spamming, beyond everybody just keeping thousand-entry killfiles.

It's also very slow. And the posting format is very hard to follow sometimes, especially when you get people that don't do hard line breaks (or the other way around, depending on the program you're using) or have funny ideas about quoting.

Also, the lack of moderation seems to create a very wild-west style of conversation, where apparently rational people can start spewing really hardcore invective at the drop of a hat.
