Well, any community that tries to show people what they want does that, including HN as it stands now; it doesn't mean you abandon the goal of getting people content they want.
It's still an interesting problem, though. You might help address it with distinct kinds of vote (relevant vs. agree), or a randomized rather than static list to show people some things outside their filter bubble, a change folks have already proposed for other reasons (it would spread some votes to things off the homepage).
I'm not sure even the naïve implementation would be so bad, though. Things from HN that have actually improved my life haven't really had a component of agreement/disagreement; often they were, e.g., tips or new things to play with or interesting CS or math.
