Xobni (YC S06) comes to Gmail

I've never understood the pitch for Xobni (or Rapportive for that matter), but maybe that means I'm not the target audience. All of the people I e-mail with are either people that I know in person (so I know what they look like), or it's a one time thing likely never to be repeated again.<p>Is there something I'm missing? I could see the value if I were in sales or some other position where I was contacting way too many people to keep them all straight in my head, but that feels like a fairly small minority of people.

It would be nice to have this and Rapportive integrate. I use Rapportive as personal CRM, but definitely some of the stats offered by Xobni are very interesting.

I think this is really smart on their part. I got super nervous about their viability after Microsoft launched Outlook Social Connector (which seems to not be as good, but is free and natively part of Outlook).<p>I've tried using Rapportive and Etacts at various times, but never really derived enough use to keep using them.<p>Also excited for an iOS app, their Blackberry app is really nice.

Any beta-testers here? Do I have to use with IMAP, or is it completele web-based?
