Meetro.com: Instant messenger geo-location social networking software
Meetro.com is a tiny geo-location social networking software, kind of like Placesite.com, except Placesite was restricted to users of a local wifi network. Meetro is more expansive and rides on AIM and ICQ networks. Basically it tells you who is nearby and gives you their profiles and the opportunity to contact them for real-life socialising. But I think the power might not be from socialising. It might be from recommendations that Meetro users make of local facilities like restaurants and hairdressers and schools. Meetro is currently only for Windows users.
