As a daily destination, Quora is no longer usable for me, no need to repeat what others already said. But the digest still surprises me and the posts are often good, even if it's a rewritten Wikipedia entry. It's like a user-generated "wonders of the past/world" newspaper for me. Daily was too much, but weekly is ok. I'm not sure whether every e-mail send it personalized, but at least in some way it looks like dependent on what I clicked before.
