Creepy or Cool?

Latitude is a free program from Google that lives on your smart phone and tracks your location via GPS or cell phone tower triangulation.  You can accept “friends” and then display your location to them (and them to you).  You have the ability to give them the most accurate location, city only, a manually entered spot, or no location at all. 

Recently, Google has taken this one step further and now you have the option of saving your constantly updated history and displaying it on a dashboard.  You can track where you have been, how far you have traveled, and where you most often go.  According to Google, this data is available only to you, can be deleted, and is not used for advertising to you.

The tech guy in me says, “Cool!”, but the man raised in an age where electronic monitoring was reserved for criminals on probation says, “Creepy.”  I can see where this would be interesting and maybe even useful, but as we all know, any information put on the internet is inherently insecure.  No server is 100% safe and no transmission is totally proof from intercept.  On a more mundane level, what happens when the NSA, CIA, or some other three letter agency shows up on Google’s doorstep with an order to surrender the records?

I’m really undecided.  Part of me is excited about seeing patterns in my life and maybe making my routines more efficient, but another part is horrified.  Opinions?  What do you think?  Are you going to do it?  Sound off and let me know, please.
