I actually was thinking about that as well on a somewhat related issue. As we gain active users it becomes significantly easier to obtain a full wheel, but after the wheel becomes full it is no longer possible (from the post) to accurately see how valued (or circled) it continues to be. I was wondering if you might be open to considering weighting the circle system as votes accumulate. Or rather if anyone thought this might be a good idea. For example, I think that the first vote a post or comment gets should always yield a circle added to the comment. But what if after that it took, say, 2 additional people to click the post before it earned another circle, or something? I don't think this is an imminent issue but I thought it was interesting. I had also considered how the speed of the site is changing.
