Shame to lose Latitude
Well this will be the biggest lose here for me... it's quick and easy with Google Maps to see where a few select friends are... I can see if my girlfriend arrived safely at her hotel after a flight, I can when my brother finally decides to drive over to my house (he's always late), I can even see where my mates are who moved to Australia and USA. Latitude is both very useful and also interesting. And it's simple enough for anyone (thinking of my GF!) to have it automatically working on her phone.
Instead we have to have G+ ??? How does live tracking work on that then? I set myself up on + a while back after various nagging by Google apps on my phone, but I don't use it, it isn't very clear how to work, I get all this rubbish on my page that has nothing to do with me. There's no way in the world I'd get someone like my girlfriend or mother to be able to use it. I don't know how live tracking works on it, do you have to have the app open for it to register your movements? Is it auto updating to selected people (not all your friends on G+)?
Latitude worked simply... your phone knows where you are all the time anyway, it's simple for it to upload that location to a central server, then your friend just looks on Google maps (which checks that server) and sees your location. It works, it's simple, it's fast, you don't need a big messy social media app just for a map.
