I recently had an idea to improve on the bubble system. I think that agrees and disagree should affect your amount of bubbles. I mean, I usually get a good amount of agrees, but I still only have one bubble. I don't mean to complain but let's be honest, people on this site are quicker to take bubbles then they are to give them. So, let's say a user is generally agreed with by the community, with not to many disagrees. Give him a bubble! If a user only has one bubble and is constantly reported and disagreed with, temporarily ban them. I haven't put much thought into this but let me know if you like the idea.
