I suppose I'm not the average casual reader, but here's my comparison--
Less Wrong front page:
-Occam efficiency/rationality games-- low interest
-Strategies for confronting existential risk-- high interest
-Potential biases in evolutionary psychology-- mid-level interest
-Taking ideas seriously-- extremely high interest
-Various community threads-- low/mid interest
-Quick explanations of rationality techniques-- extremely high interest
-Conflicts within the mind-- mid/high interest
Overcoming Bias front page:
-Personality trait effects on romantic relationships-- minimal interest
-Status and reproduction-- minimal interest
-Flaws with medicine- mid-level interest
-False virginity-- no interest beyond "it exists"
-(In)efficiency of free parking-- minimal interest
-Strategies for influencing the future-- high interest
-Reproductive ethics-- minimal interest
-Economic debate-- minimal interest
Only two of the Overcoming Bias articles were interesting to me at all; only one was strongly interesting, and it was also short. Less Wrong seemed, at least to me, to have better/more interesting topics than Overcoming Bias, which might be why it has better/more interesting discussions.
Hmm, you seem to be seeing a totally different OB "front page" to me. Where are you seeing those articles?
edit: nevermind, I thought this was the current open thread. I didn't see that it was from 2010.
This thread is for the discussion of Less Wrong topics that have not appeared in recent posts. If a discussion gets unwieldy, celebrate by turning it into a top-level post.
