Hacker News itself is rather Digg-like and quite focussed. Reddit is also quite interesting in how it lets you subscribe to reddits that interest you (and unsubscribe from those that don’t), as well as allowing anyone to make a new reddit. It prevents (or delays) the need for site migration, like what happened with the Digg to Reddit exodus, by giving you reddit migration. Don’t like /r/pogramming? Go to /r/coding! Etc.
