My 2 Cents:  Now here is a scary little app for ya iPhone users out there.  Not sure if this one will catch on but the way twitter has been going I think that this will just be another way technology will be invading our everyday lives.

Do you think that you will be ok with this sort of constant tracking system in our everyday lives?

Singles, voyeurs, lonely people, barflys, and stalkers: The new Loopt is the iPhone app for you. The latest edition of the free, mobile-focused social networking service adds a very big, neat new feature: Loopt Mix, which lets you see who’s nearby in real time — mostly total strangers.

Like Facebook, MySpace, etc., you set up a public profile, with some sparse details — photo, age, etc. — and Loopt uses the GPS in your iPhone to figure out who’s around. A potentially great way to meet people at a bar, flirt via email, whatever.

Privacy-types: It’s totally opt-in and includes a very obvious privacy warning that you must click past to use. And it’s clear when Mix is on — transmitting your location — and off. (See the red "On" in our screenshot.) So we’re fine with that.

The biggest problem so far: The ratio is a little unbalanced, if you know what we mean. Anyway, worth a shot — we’ll keep testing it out and see if different neighborhoods/times of day lead to better results.

But our long-term question about Loopt and other mobile-focused social networks is still the same: Will they be able to attract enough people to be worthwhile social networks on their own? (Loopt CEO Sam Altman tells us the service has hundreds of thousands of active iPhone users.) Or will they die a quick death the minute Facebook and MySpace add location to their iPhone/BlackBerry/mobile apps?
