I sometimes worry for a nanosecond that my zapping stuff that's unpopular or esoteric might "hurt" me, but I'm also okay with getting a feed more in my taste.

I do think this post will take on even more meaning as SN scales; right now, it's still kind of possible to keep up with all of SN's posts. There's a certain point (long before reaching Reddit levels) where that simply becomes impossible, and curating your feed/experience becomes essential.
