Not all the sites are working for me, and the little badge doesn't show any score if it doesn't have a rating from all of the sites. still can see the ratings from the sites that are working in the drop down, but needs to be able to show a score even when not every site has one. won't be keeping since it plasters the page with ? currently, and I can just look up ratings if I'm curious about a specific entry.
Edit: I apparently misunderstood the badges, they are not an average or anything, simply one of the ratings as selected in the extension. this is kinda disappointing, but at least I can select a rating source that is currently working to get something meaningful in the badges. guess I'll keep it around
