Okay, I'm not completely and entirely sure I understand what you're pitching, but I do think some of the concepts are really interesting. The idea of having an app which localizes text publishing sure is interesting, letting people send their thoughts out with a location and a timestamp. If enough people were using it, might be interesting to observe the anonymous thoughts of various localities. I'm not sure how you'd scale to more users, as it seems pretty niche, something that might only interest fun weirdos. But, with sufficiently large spatial connections, that might be fine!
I really didn't get what the "talk to yourself in layered sprints" part. I played with the tool, and I suppose it was a new idea, I just didn't really get the point. Maybe something similar could be applied in the main app, though, like having thoughts "echo" every 24h?
Overall interesting thought.
