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.
- Post one product your recommend per comment, so they can be discussed and voted on independently.
- Provide a link for purchasing the product.
- No books, movies, TV, games, or music. (These should go in other threads, like this one or this one.)
