I guess a couple of people must have clicked on the Xobni badge in my previous post, as I've been on the beta now for a week or so.

Reflections:

• I was quite pleased that it doesn't seem to slow down Outlook as so many add-ins have a tendency too. I guess YMMV but my experience was good.
• I'm not totally convinced that I'm getting huge value from it yet, beyond a gimmick.
• However, the connections and 'staying in touch' features are of value in my line of work - lots of meeting people, lots of connections.

Overall I still think that the core principles are good, and probably just some of the use cases need tightening, with a few more options - limiting indexes to certain folders and so on.
