I re-organized the badges, in Three levels following @robb advice
On average, in every community there is the 90-9-1 rule. This means that of 100% members, 90% is more or less inactive and only reads, 9% is active and posts regularly and 1% is a community promoter.
Maybe it would be nice if the badges give a more or less accurate image of these percentages in the community. The challenge is to get the active and promoter percentages above average.
