I think there's a false dichotomy here.

You want LW to feature more discussions of applied rationality, of practical uses of the mental skills sharpened here.

I want LW to feature more discussions about abstract matters, about the framework of rationality and the means to sharpen said skills.

The two aren't necessarily mutually exclusive. One doesn't have to arrive at the expense of the other. What I don't want LW to become is a Singularity cult or a personality cult, or really any kind of cult - a community where anyone not sharing the group's mainstream opinions is considered wrong by default. I'm not saying LW is or has become that - generally, I found that at least discussions of non-mainstream opinions are welcome as long as they're backed by valid arguments - but I do see signs that it can possibly turn that way.
