I don't really get how it works(mostly because I rarely use sites such as this >_>; ),
But I say again, looks neat, good luck with it!

Reddit works where everyone contributes submissions. Submissions are broken into two kinds: links and text.
All submissions are voted on, those are the arrows on the left side. Everyone can vote up or down on anything.
When you go to
www.reddit.com it shows you the big list of all submissions organized top down by vote count.
But you can go to a subreddit for example
www.reddit.com/r/funny or
www.reddit.com/r/pics or
www.reddit.com/r/wtf/ on these subreddits all the submissions have to do with a certain topic or category.
When a member subscribes to a subreddit, ie
www.reddit.com/r/reboot/ all the submissions for that show up mixed in on their front page.
It's really dynamic and for a large internet community has a lot of fun stuff and a subreddit for everybody. Puts a new spin on the normal forum way of things. Check it out please!
