Everytime a site is updated, something is lost.

World Music Network have lost the track for the Rough Guide Albums they sale.

TFL’s journey planner misses out on the wisdom of the travelling planner. There is no why on the site that people are unable to tell TFL when the algorithm directs someone to the back entrance of a hospital. The algorithm will suggest a change because according to the data it is quicker. Two routes go down the same road but one route reported a quicker travel time, so the algorithm suggests changing from the slower bus to the faster bus. yet time is lost getting off and on a bus, plus the potential the other bus will go sailing past.
