I have been thinking along these lines and collected time-stamped
tickets for some time. I plan to plot them to get average realistic
arrival times. I suspect it might actually be telling transport
planners data they don't know. It might also (rightly) embarrass them,
though that's not my specific intent (unless it makes them improve the
service or publish timetables they can keep to). They're certainly not
interested when I take the trouble to complain.

I have considered using a microblogging service something like identi.ca
(or a clone based on laconi.ca) for the real-time crowdsourcing part.

So we might even be able to increase the visibility of punctuality data
and affect improvements.

All very exciting. Yes, let's get a room, er, list for this. :~)
