I signed up because of their Clojure articles. I clicked the little stealth bomber and they let me use it without signing in through Twitter, Facebook, or Google.

They are doing a good job, but not a great job. I find interesting articles, but also some celebrity gossip will sneak in there. For example, I learned yesterday that Jennifer Aniston looks fantastic with or without makeup.

I like it, though, they find some articles that don't seem to be on Reddit or HN but which are still kind of useful.
