The second act of the check in

I think checking in could make sense as a part of something like life analytics. Maybe a mint.com for your life, where you check in (and perhaps check out) of places you go daily or weekly. You get a dashboard of how much time you've spent in each place and this allows you to recalibrate habits that have built up over time.

Do I really want to spend that much time grocery shopping? Maybe a delivery service is for me. Am I spending enough time exercising? Does my girlfriend dominate my life too much? There do seem to be possibilities beyond just "this is where I am now!"

What was the first act? Pump tons of $ into companies and never make it past the early adopters...? Outside of S.V. I don't think anyone ever checks in. I never have and I literally don't know anyone who has.
