Simple, but can you follow them?
This is a really good post from Creativity Unbound:
Here’s the take-away for the time-challenged: Three key lessons:
1. Never underestimate the power of a customer’s perception of your brand.
2. Never underestimate the power of customer-to-customer conversations about your brand.
3. Never underestimate the ability to change the perception of your brand by starting conversations with, and among, your customers using social media.
You might save this one, and read those three until they are ingrained.
Really understanding these three lessons will influence every decision you make about your brand from this point on.
