Thanks all for some of your points, I think they're very relevant. It's always important to ensure that off line as well as online are considered for your business. However, I thought that I would create a survey to understand how people are influenced by different channels- I asked 2000 people. See the results here.
I only started it about 20 minutes ago but you can see the results coming in, in real time - Pretty interesting.
Also, if you fancy asking a question, why not register and ask away. For UKBF members/readers we're offering 100 credits free (£20). Simply type
UKBF2012 when prompted for 100% off 100 credits.
