Do people want or need social location (SoLo) services?

Over the last couple of years, one of Nokia's big focuses has been on social location technology and services and I suppose it is a natural evolution in the usage of GPS technology. There have been a number of services from Nokia such as Vine, Friend View, enhanced Ovi Maps, and now Lifecasting and I have to honestly say I stopped using them after a few attempts because I personally found little value in them and never thought they were worth the hit in battery life to keep the connection and GPS receiver up or intermittently updating. I think the idea sounds great, but how many of us actually wander around the city looking for friends and people to meet up with? If I am going to meet someone then I just call them up and we work out the details of the meetup spot rather than fumble around on a phone (both parties would have to have supported services) trying to find their GPS coordinates on a map. Shoot, we could just use Twitter or text messaging too if I didn't want to talk on the phone.
