I use email a ton at work. That fact doesn’t make me special. I use more plugins for Outlook than most people. I have tried ClearContext, the David Allen GTD plugin, Plaxo, and Linkedin. The coolest so far has to be Xobni. Yes, it is inbox spelled backward. So far I think it offers the easiest look at your email from both an analytics standpoint, as well as just being plain cool. I now know, by individual, or domain, the average response time of those I email. I love it.
And to save time, yes I am a dork. No need to comment.
