This is dead on. We do Ninite support over email in our personal inboxes. I'd say the one-on-one interaction, not necessarily the phone, is key.<p>I spend about an hour each day answering it all and I've learned an incredible amount from emailing back and forth with our users.<p>It's helped us be much more clear in describing what our product does. We'd change a few words here and there and eliminate whole classes of confused emails.<p>We build relationships with our users so when we have a question about a new product, or how something should work, we can just ask some people. I love split-testing new stuff too, but that just evaluates if a change works. Talking with people helps validate your assumptions behind changes.<p>I'm sort of baffled when I see people using forums or getsatisfaction for support. You're compromising that important personal connection.<p>Also, feedback is incredibly valuable information on your strengths, weaknesses, customer desires, etc. Our main competitors have all this stuff out in the open and I love checking it out every couple days.
