I am sad that this thread fell by the wayside and that people are no longer actively throwing recommendations at it.
There was another like that some time in 2011, though I can't seem to find it. Anyway, the standard solution is to make it a monthly or bimonthly thread.
I have often benefited from recommendations for Things I Didn't Know I Wanted.
Given that Less Wrong is a community of unusually intelligent, critical, and self-improvement-focused people, I suspect we can generate a pretty helpful thread of product recommendations — perhaps even a monthly thread of product recommendations.
