The filters would get very complex very fast though, I imagine. The symptoms of "echo-chamber-itis" are as varied as the humans that exibit them. Sometimes it's aggressive downvoting of an idea that doesn't align with the status quo despite validity for discussion, sometimes it's aggressive upvoting of an idea that aligns better, sometimes it's an aggressive amount of churn as various subgroups battle for "placing" the item, which results in the item being read as a net 0. (I'm being very hand wavy and referring to patterns I see broader than just HN; before anyone starts jumping up and down about how the HN algorithms avoid any specific problem I mention :P )

You're probably right - even though I think people do want their own bubbles, attempting to provide them might just result in more complaints when the filters inevitably fail.

Then again, there does appear to be a confligt in the way the HN community seems to be growing, with the site itself still geared towards providing a relatively low amount of content through a single channel. Stories overwhelming the site and reposts are a known problem, and probably almost no one bothers watching past the first page of /news so those top 30 slots might as well be the entire site. Although, many of the most obvious remedies to this would make the site look more like reddit, and we can't have that I guess.
