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.
More and more, LessWrong's posts are meta-rationality posts, about how to be rational, how to avoid akrasia, in general, without any specific application. This is probably the intended purpose of the site. But they're starting to bore me.
What drew me to LessWrong is that it's a place where I can put rationality into practice, discussing specific questions of philosophy, value, and possible futures, with the goal of finding a good path through the Singularity. Many of these topics have no other place where rational discussion of them is possible, online or off. Such applied topics have almost all moved to Discussion now, and may be declining in frequency.
This isn't entirely new. Applied discussions have always suffered bad karma on LW (statistically; please do not respond with anecdotal data). I thought this was because people downvote a post if they find anything in it that they disagree with. But perhaps a lot of people would rather talk about rationality than use it.
Does anyone else have this perception? Or am I just becoming a LW old geezer?
At the same time, LW is taking off in terms of meetups and number of posts. Is it finding its true self? Does the discussion of rationality techniques have a larger market than debates over Sleeping Beauty (I'm even beginning to miss those!) Is the old concern with values, artificial intelligence, and the Singularity something for LW to grow out of?
(ADDED: Some rationality posts are good. I am also a lukeprog fan.)
