Here are some, based mainly on a search for which ones I've linked to before:
Distinguish Info, Analysis, Belief, Action
Two Types of People (foragers and farmers)
And, since I think he published better writings outside of his blog, here's a longer list of those:

Two posts I think about commonly are A Tale of Two Tradeoffs and This Is The Dream Time.
Others I see on the top voted list that I remember finding valuable include Politics Isn't About Policy, Stories Are Like Religion, Inequality Talk Is About Grabbing, What We Should Study, and Beware Star Academia.
But there are literally 1000+ posts, and I'd like to (as I think I've mention to you ricraz) organise a subset of them into a more readable ordering sometime.
I hadn't read "Beware Star Academia" before and it was quite an interesting concept.
This perhaps points a bit towards separate questions of "what are the best intro to Hanson posts" and "what are the best Hanson posts you might have missed if you only read the highlights?"
Edit: in particular those which aren't covered in his books.
