This is a very minor point. I'm just curious to see what the thoughts might be on this. I just "earned" a tumbleweed badge. In the past I associated badges with good things but it seems this is not always the case.
If the purpose of a badge is to inform the user about his questions then I could see the utility.
If the purpose of a badge is to contribute to the overall stickiness of stack exchange sites through a merit based reward system, I think it's less useful.
