Reddit thread about reddit's evolution and whether hubski could be the next reddit...
Like a few of the others here, this is the post that brought me to Hubski. I've haven't "left" reddit, but I like the content and style here compared to something like /r/truereddit.
Lastly, I'd like to say sorry if your site becomes overrun with a migration of redditors. From what I've seen on reddit, size can really affect the quality of popular content.
