I also like going through the discovery queues as well. I also found some good games and some bad ones as well.I try and make an effort to get all the sale-specific badges each time Steam has a sale. I got both stickers for this sale, but my Summer Sale Badge is only level 1. I too could have made an effort to level it up more, but decided against it. It's great that steam implements the trading cards and badges into their sales to get us to go through our discovery queues. Thanks to them, I've actually found games there that I've ended up purchasing and enjoying, such as Firewatch.
