> Plans are time-bound
This is exactly what I don't want. I mean, I'm no longer in the market for meeting new people (read: dating), but I can't imagine anything worse than not having a good way to politely exit an awkward encounter.
My experience with dating apps (good and bad) tells me that I don't want to get locked in with a stranger without an out, whether for dating purposes or otherwise.
Edit: I commend the originality of the idea, however.
