Achievements vs Karma - are they connected?

Is there any connection between achievements and karma? Since joining reddit a few weeks ago, I've been loving the achievements part. Something about it triggers my competitive nature, and I'm hooked on getting as many achievements as possible (today I hit my 10-day posting streak!).

My karma, though, hasn't changed. Is there a point when Reddit decides that I'm legit because of all of my achievements? Would be cool if that happened at some point.
