Blogging at

Lately I have been blogging over at our social site, where everyone interested in hazards and risk is welcome to open an account, post content, and participate.  Or just visit as an anonymous visitor and read the various postings.  I plan to use the site in my classroom teaching next winter, and it is already being used by some students at UC Davis.
