You've never discovered something and felt the indescribable, joy-inducing draw of its appeal? Listened to some music and immediately jived with it? Blaming familiarity bias and "old man yells at clouds" is a disappointingly small-minded critique. It's the opposite: I've lived long enough to thoroughly experience the joy of newly discovering something that feels like it fits me perfectly; conversely, I've tried to appreciate other things enough times to know never to waste my time trying again. Especially for the sake of others.

I've learned that liking things behaves a lot like attraction. It has no reasoning or logic, it happens organically, and when you know, you know. Thus, I would never deign to pretend to like something I've found I don't.

... but the key thing is that I am not saying that you are an old man who yells at the clouds, rather that a lot of people worry about themselves that they might be getting unduly close-minded and that this is what the blog post is trying to address.

Your mileage seems to vary, but I find that for food and drinks in particular it's the acquired tastes you get the most enjoyment from in the end -- I haven't met many people who enjoyed their first glass of peated whisky, for example. Heck, even my best friends are definitely an "acquired taste", as is obvious to me when I introduce them to other people I know.
