Social bookmarking addon (i.e. Reddit, Digg, Hacker News etc)

Hey, is there a Vanilla 2.0 addon for turning the forum into a social bookmarking site similar to Reddit? Users should be able to start discussion on a URL or a "self" post similar to the existing format. Also, topics are ordered by time and vote function rather than order of latest post.

I don't think so.
...so what is the difference you are looking for? a URL change?
Could do this in a plugin I suppose.
Looks like the voting requirement is taken care of by using the "Voting" plugin by Mark O'Sullivan.
However, I am still looking for a way for users to submit a URL to be the topic of discussion, similar to http://news.ycombinator.com/submit or http://www.reddit.com/submit. I want to avoid diving into code if possible, but I guess I could write a simple regex to detect URLs and make them clickable in titles.
