Kathy Sierra, one of the Head First authors, has an extremely useful and thoughtful post on Building a User Community. This is a post from someone who gets community, and the importance of sharing with, rather than feeding from, a community. I’m going to wait until I’ve read the sequel before I post, but you really ought to go read Kathy Sierra right now.
Teresa Nielsen Hayden, editor extraordinaire and the creator of Making Light (one of the best blogs I’ve ever seen) is not only the author of many fine posts, she also curates a thriving, active, intelligent and interesting group of readers who actively comment on the entries and on each others’ comments. A lot of that community involvement is because of Teresa’s interaction with her readers as a moderator. She offers excellent advice that is right on target for those desiring to use blogs or discussion boards for teaching and student interaction.
