Yeah, I get that. But that's exactly what I mean. If you're going to focus on Y instead of X, make it obvious why this is relevant. If not, one of two things happens: 1) it sounds irrelevant and gives the impression it's just fanboyism, or worse, 2) it effectively says "if you're not in the inner circle enough to know and be excited for the Y more than the X already, then I don't have to tell you and this isnt for you."
Which means you as the interested reader now have to go spend your precious time learning all about Y independently, from scratch, to figure out whether it is in fact important in this very specific case, or if it is just fanboyism.
Very annoying and disrespectful to an otherwise interested reader. Either state your call to action up front and why Lisp is a feature, or leave it out entirely and focus on the product.
(not having a go at nyxt specifically btw, just frustrated at the trend with this kind of titles.)
