How many emails do you get in a day? If you're like me, too many (but not as many as in the above photo -- sheesh!!). I've been trying to filter down my emails into something actionable, necessary and important, rather than a cacophony of noise. My most recent and most interesting filter has been to create a Bacn folder.
What is Bacn? Bacn is similar to Spam, except that you the user signed up to receive the messages. This can include social networking messages, blog/messageboard comments, and more. I find myself distracted throughout the day when these messages arrive, and rather than move to my next work-related email, I login to my Facebook to see what strange app I've been invited to partake in.
To remedy this distraction, simply make a new folder in your email app of choice and create a series of rules to route all social network site communication to this folder. It's as easy as that.
As it's been said, Bacn is "email you want but not right now." As is true with most things in life, with these messages out of sight, they're out of mind. I've set a GTD reminder to review my Bacn folder on a regular but infrequent basis; as such, these non-urgent messages can wait and don't stand in my way.
