Will they use it?

Librarians who serve large departments find blogs to be a useful way to communicate with faculty, staff and students (rather than emailing everyone). Would something like this work with our smaller community? For example, with fewer than ten faculty members it’s easier & more effective if I use email to communicate – especially since my faculty isn’t the most technologically savvy. Even the students have their own listservs, and again, it’s easier to email them rather than hope that they check my “education blog.” What do others think?
