I love useful infographics, ones that deliver relevant information in a visually easy to read format. The local review site chart is a great resource of review sites and lists their features broken down into visibility factors, leverage factors and difficulty factors.
A nicely laid out grid with a simple red and green palette and thumbs up or down icons. An excellent example of strong reseach for a topic in a niche industry. Delivered in a visually simple format.
