We are thinking of creating a repository of reference questions (and answers) in some sort of online system. Like those notebooks that many Reference Desks used to have, we'd enter in popular questions, like assignments, or problems that we are getting over and over. At the beginning of a shift, we can scan any new entries to see what's been popular recently.
While a wiki would probably be better long term, I'm leaning towards a blog for ease of use. It would be need to be private (password for viewing as well as posting), and searchable. It also has to be *easy*, or we won't get buy-in.
Has anyone else done anything like this, and what did you use?
