I give it an 8 because I would definitely use it again when working with a brand that has a large consumer base. Since the time I used it, many more competing tools have come out into the market, such as Crimson Hexagon, so I would recommend evaluating the features of competing tools against the business needs. Radian6 is not a one stop shop for all social media needs - it is an added layer of value over existing tools and processes, so I would only use it for a long term advertising/marketing campaign.
