Yeah, I think that a badge is special Because you cant buy it. You have to have earned it. That's what makes me think twice before I hand them out, casually.
When I received one I know that the person likely felt the same way about giving them as I did. It's a cool system.
I've not considered the ability to purchase them. We have had an experiment in the past where each hubskier had some amount of "currency" to start with and each time you shared a post or comment you gave a bit of it away to that user. Do we have a link to that experiment? mk, insomniasexx?
