Just like everyone here, I am very excited to see this new feature, which sounds like a powerful aid I may like a lot!
About the bar of 100 karma, I view it positively for newcomers. I am well below 100 right now, but I feel like to start accumulating karmas after reading this post. It is like, I can aim for goal—definite and doable—and unlock something as if I am playing a video game. So far my experience with Lesswrong was slack—I often stopped reading sequences, writing a post sounded like a distant goal, and commenting was a few time event. This is why I say 100 karma is a definite goal. I can aim at one point.
Would you consider making such milestones on karma or something? It wouldn’t be bad to add more :)
This work changed my perspective, or prejudice on fanfiction. Now I am leaning toward the art of fanfictions and I credit and thank you for all of this.
