I received this tweet (see image) today from someone who had just bought my book for their journey home and was immediately moved to tell me what they thought.
This now happens to me every day - and I'm glad to say that so far they have all been enormously positive.
While this might be very nice for me, it's also an indication of what I write about in the book in How to play the fame game. Our opinions of the products, services and creations we buy have never been so easy and quick to express publicly, and in a form that spreads.
The flip-side of this is that you can't just fake it any more. No matter how great your marketing, if the reality of what you provide doesn't live up to expectations, everyone is going to know pretty quickly. Some very large companies are finding this out to their horror right now.
It's not so easy any more to hold the public at a distance and manufacture their impression of you. Here's a particularly powerful example from Greenpeace UK calling for new logo designs for BP, to reflect their handling of the one of the worst environmental catastrophes of recent history. The designs were sourced from anyone who had design skills and then voted for by the general public.
Whether you agree with these tactics or not, Greenpeace have used them to change fundamental business strategies of powerful multinational companies.
And the most interesting part of this is that Social Media is still very, very young. Just watch what happens next...
