Like the heading says, this is my dumping ground for general ramblings about nerdy bits and pieces I've found both at work and home that might be useful to someone else, or not...Managing Your Mail
The video below is admittedly old (Oct 2007) and has done the rounds before but I only saw it recently and it’s made a massive difference to the way I work. I find myself devoting less time to e-mail but getting more done. It’s also a big morale boost to see an empty Inbox folder 
There’s a site dedicated to the practise as well (Inbox Zero) although a few of the links there are dead.
I know the video’s long, but trust me on this one. Watch it.
