It’s nice to have friends who are brutally honest with you. Say, for example, you abuptly switch from Banana Republic outfits to cowboy boots, a leather bomber jacket, and skull rings. Your friends should be first in line to intervene and let you know that it’s not working.
That kind of honesty is what you want in product feedback at the very early stages of a company. Most of us go out to “friendlies” who, not wanting to offend, tell you what you want to hear about your product (“I could see how comparing my cat’s personaliy to other cats in my area would be quite useful”). But that misdirected kindness will only cause wasted effort over the long run.
