Google announced its new feature for Gmail users called Priority Inbox last week, and there has been lots of comment and discussion about what it means for email. Essentially the new tool works out (using a secret algorithm of course!) which of your emails are important to you and then puts them at the top of the special new inbox (the old-style inbox will still be available) so you don't miss them. It's a pretty simple tool; no customisation or implementation is required. Once activated, Gmail will ask you if you want to enable the service. You can then set a few preferences (e.g. certain contacts you always want to include), but apart from that, it just works!
