Badges for patient and caregiver sounds good. Might be interesting to have distinct badges for People who are taking care of their Parents, Kids, Siblings, Other family member, or friend.
I think there needs to be some automation but potentially some manual badging as well. Some of our super users are definitely looking for quantity but there are also others who are really focused on quality. These people who have low volume but highly appreciated answers shouldn't be devalued for fewer interactions.
I've always wondered if there was a way to take "time on the site" for sessions that a contribution was made and factor that into a running clock which would then create a badge at a certain milestones. Certainly don't want someone logging in, camping out and racking in hours without valuable contributions.
I think the badges help people want to help others but really what powers people is when someone says thanks. A community of thanks. 1 Thank You in 45 responses can really charge me up to keep participating.
