I built and ran a couple of large games and sites for which I was the sole coder, the daily show runner, and the buck-stops-here responder to support requests for everything from bugs to feature requests to fan mail to "my computer crashed and I got kicked out of the game".

Building rapport is not the reason for doing this. Being liked by everyone is an impossible goal. And yes, there is a class of customers who are power users who think their input should dictate the development roadmap. And yes, there are users who become psychologically reliant on you as their personal Geek Squad. And yes, there are non-technical people who encounter hard to reproduce bugs, who it's worth taking the time to work with if they can help you isolate the problem.

But doing it for "likes" is a terrible idea. I was once put out as a coder to be a public face of a big AAA game, on their dev forum, to interact with fan requests, and I think that was catastrophic both for my own sanity and for the company that chose to field fan mail that way.

With your big fans, you see what you can do about their feature requests. Never promise anything. With people who encounter real bugs or otherwise provide signal, try to turn them into sleuths and get them to beta test your next release. Draw boundaries. Letting your users be your testers is enormously valuable, so respect them and don't stop listening to their feedback. But the overarching goal here is to get value out of the process. Explicitly not to waste your time on being "liked". Because the kind of people who become obsessive over your CS responses are actually the worst customers who don't want to pay for anything anyway, and expect everything to be free.

What I'm saying does not mean to pull back on customer service, at all! It means that the goal is to improve your product, not to suck up to all those categories of customers in the hopes they'll like you more. They will or they won't like your product, and in the end, whether they personally feel that affinity for it is based on their enjoyment of it. If it's based on their sense of importance at being able to order you around, they're not your real customers anyway.
