You can reach me at my gmail account firstname.lastname@example.org.
My main blog is currently on LiveJournal if people want to chat. There’s also a mirror at DreamWidth. Both versions usually have anonymous commenting enabled, although I may have to block or screen anonymous comments on occasion (usually when there’s a bad spam attack).
If you’d prefer something that’s occasional announcements rather than daily wibble, try my book blog on WordPress.
I’m bookfetishist on Twitter, although I can go for weeks without saying anything there.
For those who prefer mailing lists, I have an announcements-only yahoogroup plus a chat yahoogroup. You can subscribe either through the Yahoo website for the list, or by sending an email to the subscribe address.
