How much have people played around with this app? I find it both amazing and scary. Only had it running a couple of days, but very curious to see it mapping my location history. Has anyone tried the so called "routine" learning features, where it alerts you if a friend comes within range when your outside your routine locations? How long did it take to suss out your routine? I love the idea of this thing coming onstream just as the festival season kicks off. "Navigate to Jennie" is going to a lot of fun in a big crowd! But then won't Latitude be constantly alerting me everyday of the festival? Could get annoying! But I love the idea of going out on a night and using latitude for everyone to meet up. The only snag is the map scales we have currently aren't detailed enough to make it really useful. But what other uses have people found for it? Another thing I don't understand is that Google My Tracks and Latitude seem to duplicate their functionality a bit - why do they overlap them? Latitude could really be a lot of fun. Or a lot of trouble. Any opinions?
