Yeah the concept of their quarterly and anual reports reminds me very much of what Nicholas Felton was trying to do with Datum. Where Datum broke down for me was that I had to stay consistent with manually updating it.

Good point. You don't mind something that automatically tracks you (gps, events, etc), it wouldn't creep you out?

and we were quite inspired by Nicholas Feltron's work also. I think they're amazing.

This is the big challenge when it comes to quantified self -- passive tracking can be creepy, but manual track has such high adoption costs. Seems like it would be hard for manual tracking to go extreme, bc few people care as much about quantifying everything as this community does. Any form of passive tracking has higher upside but also must be treated carefully so it seems trustworthy.

I agree.
