Sites like Hacker News and Reddit provide for their users one or more ‘front pages’ containing interesting posts that have been up-voted by the community and are popular at a particular moment in time. However, out of these posts, the user is unable to configure the topics on which he wants to see posts, and the themes that he doesn’t want to see. that is exactly what subreddits on reddit are for. subscribe to the subreddits you care about, unsubscribe to the ones you don't. your front page will then be customized to show you stuff you'll want to read. do many casual reddit readers not know about this? the only difference here seems to be that a single link can be tagged with multiple tags, as opposed to reddit categorizing links with one category (though the same link submitted to multiple subreddits are linked together through the "other discussions" tab, but discussions are separated).
