Personally, I don't buy too deep into v4 causing Digg's death. It certainly helped, but stuff like seeing "mrbabyman" and a dozen other power users controlling all the content became tiresome well before v4. Reddit was a little refreshing as I could post in a subreddit and have my content get a fair shake at being seen. That's still true today. My blog and my old webcomic have both been at the top of /r/comics and /r/android. The traffic and exposure was very nice and I think the upvote process is mostly fair. With sites like Digg or Slashdot there's zero chance my stuff would have gotten any exposure.
