Dopplr went after the conference/business market, and at least in my crowd it had critical mass. That might be because I know the founders...
But it cracked OP's issue of needing daily use so you remember the service. I would check Dopplr to see which of my friends were coming to London -- that's much more frequent than me travelling, to the tune of travel_frequency * friends / cities. It was useful, and I still miss Dopplr today.
