I have a few invites to the Xobni beta. Let me know if you’re interested by commenting (put your email address in the e-mail address box) and I’ll send over as many invites as I can cover.
I installed it yesterday, and it’s actually a really cool way to see stats on your email for people who like that sort of thing. Here’s a few samples:
Communications with my boss: I can clearly see that they typically happen during the day and not in the middle of the night. That’s a good thing. 🙂
There’s a lot more super-cool views, but I can’t really sanitize them sufficiently to display here. One of the cool features is the “Stay in Touch” view – it shows people that you haven’t emailed in quite some time, and it’s reminding me that there are a bunch of people I need to chat with again soon that I haven’t in a long time. Neat stuff.
