No, reddit is a web site where users can submit links into a nearly infinite number of subreddits (kind of like starting a thread on ChiefsPlanet). Other users then "upvote" or "downvote" those submissions, which determine how high the link shows up on the "front page." They use a time-based algorithm, so topics that are new and active end up on the front page, but eventually get replaced by new stuff, so it's a constantly changing "front page of the internet."
The normal front page itself is nifty for killing some time, but the real value of reddit exists in its various subreddits. If you sign up for an account, you can pick and choose which ones you want to show up on your own personalized front page. If you get rid of all the defaults (which are largely full of crap submissions these days), you can really find a cool way to find links you're interested in quickly.
