OK, I'm a geek. My
earlier suggestion really was half-serious. I agree with
Joel that the reputation dot scale shouldn't be tied to any one CD member; however, I still like the name "deciBaker" to indicate a user's reputation in number-of-dots.
To remove Andy's actual reputation point total from the equation, I proposed this alternate definition of the deciBaker:
dB = 1 + 10*log10(reputation point total / 100)
Number of dots would be equal to the next higher whole number of dB. So a member with up to 100 (positive) reputation points would get one (green) dot. Dots would increase with increasing reputation point total, with each dot successively harder to get than the one before it:
1 dB = 100 rep points
2 db = 125 rep points
3 dB = 160 rep points
4 dB = 200 rep points
5 dB = 250 rep points
6 dB = 315 rep points
7 dB = 400 rep points
8 dB = 500 rep points
9 dB = 630 rep points
10 dB = 800 rep points
11 dB = 1,000 rep points
12 dB = 1,250 rep points
13 dB = 1,600 rep points
14 dB = 2,000 rep points
15 dB = 2,500 rep points
16 dB = 3,150 rep points
17 dB = 4,000 rep points
18 dB = 5,000 rep points
19 dB = 6,300 rep points
20 dB = 8,000 rep points
21 dB = 10,000 rep points
22 dB = 12,500 rep points
23 dB = 16,000 rep points
24 dB = 20,000 rep points
25 dB = 25,000 rep points
etc. (no upper limit)
Under this system, they're not just dots -- they're deciBakers!
And since there would (eventually) be more of them, there would be more styling potential; e.g., cool shapes, pretty colors.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
