Anil Dash has a post today about diamonds, following up to a post he did four years ago. I'm not sure how I feel about buying diamonds myself - I oscillate between not-so-bad-if-you-know-they-are-conflict-free to industrial-diamonds-only to none-at-all.
I definitely think it's worth knowing where they come from if you are intending buying them, though.
I was looking forward to seeing the movie, but after reading the first comment on Anil's blog, I'm less inclined. If Warner really did promise artificial limbs to amputees they hired as extras, and has reneged on that promise, they can whistle for my $9.
