It's also been a very useful exercise. Always good to experiment rather than just speculate.
I think I've proved to my own satisfaction that pushing the contents of low volume lists out to rss feeds is a valid way of getting information across
- Human Factors: depending on the blog aggregator used the occasional appearanace of a low volume blog is more likely to be read than an adminsitrative email that can be lost in a slew of other messages
- Ease of distribution: other than getting people to actively subscribe to the feed there is very little administrative overhead - certainly far less than in managing a traditional listserv
- Lurkers: this mechanism peple who wish to lurk, or who only wish to follow do so, again without an adminsitrative overhead
