Yes, the demo is old, but I think the direction of "it searches for this, this and this" is weak. It'll be too easy for them to have focused on integrating more services. Actually handling something like dinner organising or flight booking has its own foibles and caveats, and while I believe it can be done, I think the best way to start doing it will be focus.

I'd pay for a tool that helped me organise social events without the irritating e-mails. Take Doodle: all it does is polls for dates, and it doesn't handle diary integration, contact integration, negotiation of possibilities, or choosing the place as well as the time. Despite those shortcomings, its a successful company. That's where I see an agent actually working.
