With the introduction of reporting badges on the horizon we should consider introducing badges for other things. Most importantly I think looking at the possibly of rewarding a badge for setting a custom trust list. The trust system is wholeheartedly broken and theymos has even said himself its not working as intended. We are not sure of the positive effects that badges bring at the moment. But this is why reporting statistics should be released before the implementation of the badges and then after an initial period (3 months) we should look to see if this has increased the number of reports being made.
If it has then we have hit the jackpot and the status of getting a badge encourages members to do things that they wasn't doing before. Therefore the trust system might not be doomed after all and might only need minor adjustments in the future if we were to implement badges for creating a custom list. Among others things too. Reaching milestones of posts, time signed in or merit gained.
There is a reason why universities reward virtual badges now and its because people love to show off to other people their accomplishments and making the badges stand out without being annoying is a great way to improve things without even....well improving things.
