The changelog for 0.11 does say something about the karma system, but it's not clear to me if the has actually advanced to the stage that it leads to genuine unique comment. If my understanding is correct, prior to 0.10, the karma system did nothing (and may not even have really toted up the karma points). My understanding was that 0.10 laid down the underpinnings for karma actually doing something in the future, so it's possible that it actually does something in 0.11. Personally, I'd love to see someone post when they find something that is genuinely different and limited by the karma score. I pretty much took it as a indicator of whether I was playing as a nice guy or as a jerk, in case the actual decisions didn't make that clear.
And (tacking a horse onto my above cart), I wouldn't expect that particular progression to change unless it's somehow tied to karma.
