Seems like Microsoft has gone and created some pretty interesting software (that, not suprisingly, plugs into a pre-existing piece of MS software) that will rank emails in your in-box not on time of arrival but on SNARF’s perceived importance (i.e. someone who is in your address book, someone you’ve replied to often). I don’t suffer in-box drowning, but know many people who do (my supervisor, for example). Might be a solution. Only problem? Hafta use MS outlook.
