The reactionary approach to PR simply doesn't fit with the speed and efficiency of today's ultra-connected world.
The time taken for perception to change, en masse, is HOURS not days, and definitely not weeks.
It will be interesting to see how many more companies have to experience disasters like this before realising that their entire PR mentality needs to be re-booted.
In London, the TFL had such a realisation here: http://www.jonathanmacdonald.com/?p=4330
And these cases are just the start.
With over 100 million blogs and the general public increasingly being able to create, edit and publish, this isn't a fad - it isn't a blip....and now its time that companies such as Toyota realise this - or live in a perpetual recovery period.
